Remember the movie Step Brothers? Possibly the funniest movie ever created. In the movie they said "lets fuck shit up." FSU is an easier acromyn for the term "fuck shit up." Use this term to say your about to party, or just do anything awesome or fun.
We're about to FSU tonight.

Let's FSU at this party.
