1) The character from Borderlands 2, a pony made completely out of diamond by Handsome Jack, the game's Antagonist.

2) A man who has lots of anal sex with other men, the male version of "pussy-hound"
1) My favorite character from Borderlands is Butt Stallion.

2) He has had a lot of sex with other guys, that butt stallion.
