Imagine that your butt has epilepsy and was exposed to too many flashing lights.

The act of shaking your ass like crazy
You can make it wobble, boomerang, bounce, clap, etc.
Usually done by black girls with big asses.

Redneck: To get something done.

Ghetto dancing

A "dance" demonstration of a "hoe's" body and sexual prowlish as a means of "proving" the value of a pimp's "stable". The moves, choreographed to beats of heavy hip hop music, focus on the buttocks, pelvis, thighs, and legs. Nearly gymnastic moves feature pelvic thrusts, shaking and quivering buttocks, bouncing leg splits with vaginal thumping on the floor, and shaking and grinding buttocks while bent over to simulate copulation from the rear. Contrary to its current fad status as a club dance, twerking has been a staple since 1974 when the pimp "Bishop Don 'Magic' Juan" organized in Chicago the first "Players Ball". A film, "American Pimp" (1998) included a clip in which "hoes" twerked in front of their pimps and others. Subsequently, twerking was adapted by strippers and exotic dancers to routines they performed in clubs.
