rynnäkkökänni 

Finnish activity.

Translates somewhat directly to assault-drunk, commonly used to describe getting as royally bladdered as fast as you can. Imagine if drinking was a legit military activity, and your CO yelled a direct order at you to "get the fuck out of your mind".

"Vedetään rynnäkkökännit" (let's get drunk like you've never done before)
