In a car that is equipped with some sort of forced induction system ,such as a turbo or a supercharger, a blow-off valve is usually availible as an aftermarket part to release excess pressure (boost) from the turbine system. Makes a very distinct noise. Like - pssssshhhhhhhhh! Or somtimes a chirping noise depending on the blow-off valve. Usually replaces a stock part usually refered to as a by-pass valve.
1. Gil: Whoah, dude! Did you hear that car go by?
Willy: Yeah, it sounded like it had a blow-off valve.

the nasty farts you rip when you've gotta take a dump. smells worse because the fart is passing over the turd lodged in your ass. also known as an "omen fart."
i knew we'd have to pull off at the next rest stop, because shauna had been blowing off a log for the last five miles and i had to roll down the window.
