The "Oh Yeah Face" is given to either sex in one of two situations:
1. The face given to a sexy woman to silently exhibit a man's sexual acceptance.
2. The face that Man One gives Man Two, about to bring up the topic of the Man Two's sexual partner.
2. I gave Jeremy the Oh Yeah Face, and proceeded to bring up his sexual partner.
"Man, Jeremy. I wanna take your girlfriend and scrub her up and down with my tongue."
