A French fry that falls out of its container and onto the bottom of a paper take-out bag. Sometimes found in twos, other times found in large groups with other bum fries creating a greasy bottom. Bum fries are in no-manâs land, hence are up for grabs by any party that shares the same take-out bag.
Friend 1: âHey! Stop eating the fries from the bag, those fell out of my box!â
Friend 2: âNah man, thatâs just a Bum Fry!â
