A sexual act in which a woman's vajayjay flaps are stretched out using a large rubber ball. Stretched out to the point where they resemble Dumbo, the flying elephant (dis is the point of no return). The man, or woman then flips the stretched one over, onto their head and uses the flappy flaps as wings. They fly over the colonies, dropping bombs and taking names. People get mad and scared. You have to start blocking your windows wit black fabric they will find you though, they always find you.

Regarding fighting (Mixed Martial Arts, MMA, UFC or Boxing) when a fighter is punched in the head so that, in slow motion, you see his cauliflower ears flap around like the animated Disney character "Dumbo".
