AUUU

An exclamation used to express happiness and/or satisfaction after completing a task or under the influence of drugs. It is often preceded with a phrase of little to no meaning.
The expression can also be used spontaneously in moments of excitement and happiness.

The origin of the expression goes back to 2017 when it was first used by DJ "Szmitek" in one of his mixes published on YouTube.

Person 1 - "Kill me with a dildo! AUUU!! AUU! AUUUU!!!"
Person 2 - "Wow, you seem really excited! What happened?"
