look up any word, like thot:
 
1.
The gap in your legs when you lift your leg in front of you creating the shape of the number 4. Used in the game hackey sack/footbag.
Playing hackey sack, a dude goes to hit the bag up with his foot, but misses. The bag goes in the gap between his legs and crotch.
Dude 1: Aw man it went in my 4 hole.
Dude 2: It always goes in your 4 hole
