A sharp, wet, fast farting sound. Usually made with tightened butt cheeks with the person in motion. Very similar to a car's backfire in that it's a totally unexpected and loud sound that startles.
Damn, dude! That crackfire scared the shit out of me! And it stinks, too! Better check your drawers after that one!
