Female pubic hair that reaches 1-1.5 inches below the belly button, depending on body type. Reminiscent of a dark colored shag carpet sample and not to be confused with a happy trail.

My friend Dan turned into a Holla Monster last night at the bar. I understand he hasn't had a date in a long time, but he literally tried to hit on every hot woman he came across.

Kim: Oh, I'm sorry for yelling.
Zach: Damn right you are! (slaps Kim's ass)
