Is this action completely insane or weirdly justifiable?
You be the judge.
If you thought everything Carrie Underwood did to that guy's car in that song about cheating was unforgivably terrible, you probably shouldn't watch this video of a lady who literally sets this guy's unfaithful penis on fire.
It's less “maybe next time he'll think before he cheats” and more “this man has no more penis." His penis is a bonfire, and you can't cheat with a bonfire as a penis.
Let this be a lesson to anyone weighing the pros and cons of infidelity.
