RACK

What does RACK mean?

RACK stands for Risk-Aware Consensual Kink: kinky play in which the participants know the risks in advance, name them out loud, and choose them together. The framework trades the word safe for risk-aware, because nothing is completely safe. There is no settled Dutch translation. Chronologically it is the middle one of the three acronyms circulating in the scene.

What RACK means in practice

Like a conversation in which the word “safe” is never spoken.

Anyone who keeps to this framework replaces the question is this safe? with three others: what can go wrong here, how likely is that, and what do we do if it happens anyway. That sounds businesslike, and it is.

A concrete example is breath play. That is the corner where things have gone wrong most often in the past, and where drink or drugs played a part in most incidents. So a RACK conversation about it is not about whether it is safe, but about who stays sober, about who knows what they are doing, and about whether you want to take this risk.

Where RACK comes from

From one man, on one mailing list, in reaction to one word that bothered him.

Gary Switch describes it himself in the essay that later appeared in Prometheus: during a discussion about SSC on the TES-Friends list, he proposed RACK as an alternative. The exact date is not in his own piece but in someone else’s: slave david stein, the presumed author of SSC, notes in a footnote that Switch coined the word on 25 November 1999 on the TES-Friends list and published it in Prometheus #37 of May 2001. His reasoning opens with a line that has stuck in the scene: nothing is completely safe, crossing the street included. If you want to limit BDSM to what is safe, he writes, you are left with nothing that goes harder than hitting someone with a wet strand of spaghetti.

Then comes his comparison with mountaineering. Climbers do not call their sport safe, for the simple reason that it is not; the risk is part of the thrill. They deal with it by recognizing it and reducing it with study, training, technique, and practice. That is exactly the attitude Switch wanted for the kink world. And about negotiation he was brief: it cannot be valid without foreknowledge of the risks, because if you do not know what is really going to happen, you do not know what you are agreeing to.

The K in it, by the way, was mostly there for the rhyme. Switch writes that kink made the acronym sound good and said right away what it was about: SSC, after all, does not say what you are supposed to be safe, sane, and consensual about. Safe, sane, and consensual trout fishing?

Why people say RACK rather than SSC

Because one word from the older framework turned out not to hold.

D J Williams, Jeremy N. Thomas, Emily E. Prior, and M. Candace Christensen explain in their article in the Electronic Journal of Human Sexuality what happened in the switch: safe was replaced by risk-aware, but the more striking thing is that sane dropped out entirely. That word assumes a norm of psychological health, while “sane” is strictly a forensic qualification used to judge whether a serious disorder underlies a crime. For tuning an evening that term is of little use, they write. On top of that, “sane” in practice calls up negative stereotypes, and for part of the scene that is reason enough in itself to prefer RACK.

What it yields differs from person to person:

• For you RACK means you may ask what can go wrong without it sounding as if you doubt the person across from you. The question simply belongs there.
• For the other person it means he no longer has to promise that something is safe. He may say what the risk is and how he keeps it small.
• For the two of you together it yields an agreement specific enough to keep.

The framework meanwhile solves nothing. Williams and colleagues note that the word risk itself also carries baggage, because it is firmly tied to the language of medicine and public health. And a four-letter slogan is no replacement for a conversation.

Misconceptions about RACK

“RACK means anything goes as long as you know about it.” No. The framework moves the bar from safe to informed, and leaves untouched the question of whether you want this. Boundaries and hard limits stay exactly what they were.

“RACK is something for advanced players.” That is the most dangerous one. In the incidents about which anything is known, those involved were precisely not newcomers to BDSM. So experience is no replacement for risk awareness.

“RACK has replaced SSC.” They exist side by side. The English-language encyclopedia notes that not every practitioner keeps to one framework; there are those who name one to outsiders and the other among themselves.

What I see myself

I’m Victor. Gigolo, twenty-five years in this work, and trained as a psychotherapist besides. This acronym reaches my inbox more often than the other two, also from women who otherwise use not a word of scene jargon.

Most know the R and the C, and skip the middle part. “I know there is risk” is not risk awareness, that is an attitude. Being risk-aware means you can name the risk. Which nerve, which spot, which substance, how long.

I also hear the word used to close a conversation rather than open one: we do RACK, so that is settled. Then it has become a reassurance, and that is what it was never meant for.

What you can agree with RACK

• Ask about the concrete risk of this proposal, not about the risks of BDSM in general; an answer that applies to everything applies to nothing.
• Agree who stays sober. In most of the known incidents, drugs or alcohol were involved.
• Have the other person name how they make the risk smaller, because that is exactly the knowledge Switch compared to the mountain climber.
• Ask what happens if it goes wrong: who calls, who stays, and what is said to a doctor.
• Repeat it each time. A risk you weighed last month is not automatically the same risk when you are tired or have a cold.

More on RACK

On this site informed consent explains why knowledge and consent are tied to each other. The 3V’s give the Dutch trio of the framework RACK was a response to, including the coiner’s own look back. And negotiation is about the conversation itself, with the 4Cs alternative included.

Where this fits on this site

If something concrete is on the table, you want to hear how that weighing sounds. On the consent page you can read which questions I ask before anything begins, and how you can still change your mind halfway.

Candace Christensen, Electronic Journal of Human Sexuality 17, 2014. Read via the web archive; ejhs.org is offline. Provides the statement that RACK was coined by Gary Switch, that in the switch safe was replaced by risk-aware and sane dropped out entirely, that “sane” is strictly a forensic qualification serving to judge the causality of a serious disorder in a crime and therefore has little practical use for BDSM negotiation, that RACK arose from the recognition that motives and risks differ strongly per participant, and the note that the word risk itself is anchored in the language of medicine and public health.
