Top Definition
One who does not flush the toilet after pooping in a public bathroom. Stacking toilet paper on the water pre-poop to ensure the poop stays above water level is optional. Main goal of the "NFB" is to stink up the bathroom/clog the toilet for the next, unsuspecting user.
The No Flush Bandit struck again, this time in the food court bathroom at the mall.
