Crotch Vomit 

Child or baby - typically one that is screaming, stinking or otherwise unpleasant to be around.

"I was trapped on a plane with someone's crotch vomit in my face for six hours!"

Vomit Crotch 

What your crotch smells like after receiving oral from a drunk hooker who couldn't hold it down.

I picked up a drunk hooker, but she threw up while giving me head. Now I have vomit crotch.
