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.

Get the Dumbo-Assomug. When a chic convinces a dude that the best manscape technique is shaving everything above the shaft but growing the ball and ass hair as long as possible. From a profile perspective, the package will look like Dumbo with a mullet.
“Bro did you see coach’s nuts when he sat down at the picnic table? He was rocking Dumbo’s Waterfall no cap.”

Get the Dumbo’s Waterfallmug. 
When you trying to be nasty about taking your own clothes back thinking it belongs to the other person because we all know it looked better on the other person.
