We have come across so many stories about people stealing their roommates’ things and not even feeling guilty about it. They only stop doing it after they are taught a lesson, so here’s another humorous, petty revenge story that you might enjoy.
It all started when the original poster’s (OP) roommate kept stealing his ice cream, so he took mint chocolate ice cream and spiked it with pure extracts of menthol and capsaicin. The thief’s mouth was probably on fire from all that spice and now he straight-up refuses to eat that flavor ever again!
