The jiggling fat build-up at the end of your tailbone. Usually used to grind, break-dance, or utilize in other types of dance. Sometimes both booty-cheeks (butt cheeks) slap or rub together, causing a "grinding", "jelly-like", or "slapping" sound. This is normal. Booty's are used for music videos such as "Ms. New Booty," by Bubba Sparxxxx. The booty acts as a balloon filled with Jell-O or a firm sack that has freedom of movement. Large booty's tend to appeal to men. Chunky booty's, however, do not appeal to both gender categories. Booty's can be referred to as butts, bootays, bottoms, behinds, rumps, tushes, funk machines, jiggle makers, slap sacks, donks and/or badonkadonks. Slapping or squeezing the booty can cause it to explode, pop, or expand.
