Jaca
Jaca blau is French for 'fuck off you cunt' and also means 'suck your mudda' in the language of roadmanians, which is basically the language of people who know nothing but how to swear.
My brother texted me 'jaca blau' because I told him his haircut was worse than a bad pizza.
My crush called me 'jaca blau' after I failed his math test.
That guy in the DMs said 'jaca blau' and then left.
