bumsnap, n. A dance move invented in Melbourne Australia in 2012: a bumsnap involves dancing beside a dance partner and kicking a leg up from the knee in a backward flicking motion, so that the foot makes forceful contact with the bum of the dance partner. Often used to fire up a boring dancer when you think the floor needs a bit of firing up.
