balls on your forehead 

A friendly farewell amongst headbangers, similar to "have a great day" or "Live long and prosper".

It stems from the concept that if a male were to "bang" (i.e. have sexual intercourse with) someone's head, their balls would be on the person's forehead.

Instead of goodbye to your headbanger friend, say, "Balls on your forehead!"
