Hmmm. Hmmm.

An often used expression from the Regular Show used as an affirmative statement and
also as a sarcastic way of saying "I told you so" or "You are ignorant".

After blocking a death punch from Rigby, Mordecai said
"Hmmm. Hmmm. You are never going to beat me at punchies!"

HmmmYouDontKnowIt 

Some retard on this godforsaken website who is incapable of being funny, ironic, and relatable.

HmmmYouDontKnowIt is a prime example of why a mentally stunted child should not be exposed to the internet. #AutismSpeaks 2022.
