RUSM

What does RUSM mean in messages?

Are you s******* me

Censored

RUSM is a blunt and often humorous way to express disbelief, surprise, or annoyance. It essentially means "Are you serious?" or "Are you kidding me?" but with considerably more attitude. Since it contains implied profanity, RUSM is best suited to casual conversations rather than messages to your boss about next quarter's budget.

No single person created RUSM; it developed as shorthand in texts, instant messages, forums, and other online conversations as a variation of "RUKM." Someone might send "RUSM?" after hearing something ridiculous, receiving unexpected bad news, or wondering whether a friend is pulling their leg.

Example

they moved the deadline to tomorrow morning

nope. just got the email

That RUSM feeling
