ass clap

A character rhythmically and vigorously claps or slaps their own buttocks together, producing a visible ripple/jiggle effect and often an implied (or explicit with sound) clapping noise. It is a specific form of twerking or ass-focused animation emphasizing the impact and collision of the cheeks.

This tag is almost exclusively used on animated or video posts, as the motion is the core element. Static images may use related tags like ass shake, bouncing ass, or ass ripple instead.
