When you unexpectedly give someone laxatives, and they unwillingly vacate their bowels, that is what we like to call "turd burgling".
Last night was insane; we were turd burgling like some 'shit witches' last night.
The people who go around dosing people unwillingly with laxatives in order to make them shit themselves.
See: "Turd-Burgling" / "Turd-Burglars"
I saw like 5 people shit themselves last night; the Shit Witches must've been out in Full Force!
