A pre-oral sex practice of kissing around a womens inner thigh area in an attempt to detect a foul smelling vagina. If a foul stench is encountered, the man moves in close and takes a mouth full of the air near the pussy hole. He then crawls back up to kiss her on the face right after exhaling into her nose.
I threw up on her panties before i had a chance to even go mouth fishing.
