(almost always found in petite women) a completely shaven, tiny, tight pussy. One finger is already tight, and it's a bit of a struggle to get a second in. If the woman is under 5'4" and isn't a huge whore, chances are... you might be hitting up some baby pussy. Another characteristic required is no visible inner labia.
Drunk Guy 1: Dude, I bet she has a small pussy cause she's so short and skinny.
Drunk Guy 2: Yeah, man... baby pussy is the best. That girl, Sam, looked like she'd have some baby pussy.
Drunk Guy 1: You wanna get some more beer?
Drunk Guy 2: Nah, I'm just gonna call Erika over and hit up some baby pussy.
