O!RUL82?
This is what you say when you're not just late, but you're also being a total mess about it.
O! RUL82? You’re late and you’re still doing your own thing like nobody else matters.
O! RUL82? I could’ve been done with this party before you even showed up.
O! RUL82? You’re like the last domino in a game nobody wants to play.
