someone who hates themselves because they fucked up, and then fucks up more because they hate themselves for fucking up. The semi-fuck-up can be cured, but for a full on case, there is little hope.
John walked to his friend's house, and on the way, he realized he forgot to bring his buddy's xbox controller to give back. John realized he'd fucked up. Then, John got mad at himself for fucking up the xbox situation. He then proceded to be a douche to everyone he saw for the whole rest of the day, just because he forgot the controller. Then, he got pissed at himself for being a douche, and did lots of drugs. John was a fuck-up. He just couldn't stop fucking up.

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
