look up any word, like donkey punch:
 
1.
Is a style of hair worn by men or women whose hair is long enough to pull into a pony tail, but it is too short to actually form the "tail". Thus creating a ball of hair hanging delicately on the back of their head, vividly resembling a male scrotum.

Derives of the words scrotum and pony tail

Found commonly on tom boys, middle aged lesbians, and artsy males who wear stylish ascots.
Co-worker 1: Have you seen Gary's hair today?

Co-worker 2: Yeah. When he walks it bobbles too and fro. When he stands it just hangs there useless and annoying. Kinda like a ball sack.

Co-worker 3: Oh...he's probably going for the Scrote Pony Look
