*having sex in the ear*
The sensual and unspoken act of inserting ones penis into an ear cavity. Ear penetration can spread STDs, so, use an ear diaphragm.
Mike - "Did you guys hook up last night or what?"
Ned - "Oh man, the best earsex of my life last night. So hot right now."
A hot guy is an earsex. An okay looking guy is an earfart, and an ugly guy is a dogfart.
P: No way, total earfart.
J: Na uh.
