A humorous, euphemistic way to refer to the act of committing suicide. It is a play on the Australian slang expression "chuck a u-ey" for a u-turn. It is used typically by teens to be able to address the taboo topic rather than avoiding the negative stigma.
"Ugh I have 7 exams in the next week, makes me wanna really chuck a su-ey"
