Cake That
This act of revenge didn’t result in a big mess to clean. This person just wanted to prove a point to their partner who just got caught cheating. When the cheater came to their car, they found a perfectly good uneaten cake smeared on the back window with a not-so-sweet message taped down.
We have to wonder how hurt this person was or how much they cared. Maybe they just have absolutely no creative skills. This really isn’t a giant mess to clean up, and it’s not an emergency since you don’t need a clean back window to drive. The worst part about this revenge is that nobody was able to enjoy the cake.
