The giant ass of a baller. Generally refers to an ass with such great volume, it actually possesses its own gravitational pull. Can also be used in reference to the person who posseses said ass. Ex. Hey look at that Thanus! Has the biggest but on the team besides the fat kids!
Ali: Hot dang! check out that fine thanus! I love football players
Christine: He does not even need to tackle the other team man. All he has to do is sit, and there goes the team!
Ali: Break me off a piece of that!
