Crack

Definition
Within BDSM, crack usually refers to the sound and sensation of whips or floggers cracking through the air and making a loud bang (“crack”). The word can also be used to describe the sharp sensation of the strike itself.

Explanation of crack

The phenomenon of crack, or “cracking,” is mainly associated with whips such as the bullwhip or singletail. When the whip is swung through the air at speed, the tip (the cracker) reaches supersonic speed. This creates a loud bang, similar to a mini sonic boom. This sound alone can have a strong psychological impact on subs: the anticipation, tension, and threat often make as much of an impression as the actual strike.

Within BDSM, crack is experienced in two ways: as an auditory stimulus (hearing the bang can already transport someone to higher realms) and as a physical stimulus (feeling the sharp, cutting blow on the skin). It can vary from playful threats and show elements to very painful impact when actually used on the body.

Consciously producing the crack

For many Dominants, mastering a whip and consciously producing the crack is an art in itself. It requires technique, precision, and practice to make the whip crack safely without accidentally injuring the submissive. Within the community, “cracking” is often seen as a performance, for example during demonstrations or shows.

Term What is it? (Explanation)
crack The sharp sound a bullwhip or stockwhip makes when its tip (the cracker) breaks the sound barrier. The “crack” is a tiny sonic boom used for rhythm, precision, or signaling. It does not necessarily involve striking the skin and is often part of performance or warm-up technique.
cracking The act of making a whip crack by propelling and snapping it in a controlled motion. It’s achieved through acceleration and wave transfer (for example, C-swing, overhead, or figure-8) where energy travels through arm, wrist, and timing to the tip. Requires space, awareness, and practice; hearing protection can be wise for prolonged training.
cracker The thin, replaceable string at the end of a whip (also called a popper) that catches the air and produces the crack. Usually made of nylon, paracord, or Kevlar; its length, thickness, and material affect loudness and tone. The cracker is a consumable part and is replaced regularly for performance and safety.

Safety & points to note

Properly cracking a whip requires a lot of training. Untrained use can lead to serious injury.

Always keep enough space when practicing; a whip can reach meters and be dangerous to bystanders.

Avoid the face, neck, spine, and joints. Aim for more robust body parts such as the buttocks or thighs.

If necessary, wear an eye mask or safety goggles during practice to prevent accidents.
