Tripping the Breaker
Without any embellishments, the girl places the guy's penis in her mouth. Then as clearly as possible she says a disturbing or entertaining movie quote. After which she simply removes the penis.
Tripping the Breaker: For a guy about to go off for army training. Place his penis in your mouth. Say, "Only two things come from Texas, boy, steers and queers, and I don't see no horns on you." (Best if you're in Texas.)
