1. a term used to describe sharting (farting but shit accidentally comes out) while dancing at the Florabama (famous bar on the Alabama/Florida border) usually caused by bushwackers or any other milk-based drink. Usually requires a "back it up" style dance in order to try to save yourself.
That guy had 3 bushwackers and is shancing all over the place.....get him out of here.
