An academic or work related tactic used by mainly students that involves the act of staying up all night in order to complete an assignment or deadline. This usually leads to a day full of absolute fucking dread that wasn't worth it, and this tactic is used by either really smart students who are selling their souls to keep their 4.0 gpa or procastinators that actually have a life.

Or an All Nighter is used by weebs who wanna watch "One more episode".
