Speeding in a School Zone 

A term for masturbating/ejaculating. The term comes from the fact that the average speed of ejaculation is 29 MPH, while a school zone has a speed limit of only 20 MPH. Thus, your ejaculate would get ticketed for speeding in a school zone.

Frank: "Dude, I was just speeding in a school zone before I got here."
