Fuckburnt (adj.)
1. The state of being in deep trouble, embarrassment, or an awkward situation, often due to one's own stupidity.
2. When something goes so wrong that it metaphorically burns your reputation, dignity, or social standing.
3. A combination of "fuck" (because, well, it's bad) and "burnt" (because you're roasted, metaphorically or literally).
–Bro, I accidentally sent my boss a meme that was meant for my friend. Total fuckburnt.
–She tried to lie about being sick, but her Instagram story showed her partying. Ultimate fuckburnt.
–He parked in a handicapped spot and got his car towed. Straight-up fuckburnt moment!
Almost synonymous with cockblock, but worse. Someone who constantly thwarts sexual encounters out of jealousy because they have no game. Can single-handedly ruin a party unless immediately kicked out.
