fan your boner

relax, chill, stop being so overly excited, there's no reason for alarm, it's all going to turn out okay. Also, don't count your chickens, and don't assume that sex is imminent or that something else very good is about to happen.

Dude, fan your boner. She was only dancing with you to make her boyfriend jealous.

Okay, okay. Fan your boner. There's gotta be somebody around here who can give us directions.
