The Brief: Me RN means "me right now."

DEEP DIVE
The phrase “me RN” captures one’s current mood or feelings. It is used in conjunction with photos, videos, or text that describes one’s present point of view, usually in an exaggerated way for the purpose of comedy. The phrase can also be paired with IRL (“Me RN IRL”) for extra emphasis.
