f-tup
A secret code for being totally messed up. People use it when they can't say 'fucked up' because it's too loud or too obvious. It's like a sneaky swear word.
My math test was an f-tup. I drew a cat on the answer sheet.
The lunch lady dropped the soup. It was an f-tup.
My dog ate my homework. That was an f-tup.
