Means to get sacked, dumped, or kicked out of something, usually without much warning. It’s the brutal, final kind of exit, like a guillotine but with more paperwork. Used for jobs, TV shows, teams, even mate groups when someone’s been a bit of a melt. Honestly, it always sounds harsher than it needs to.
