1) the feeling you have when you've hooked up with the same person before but you dont remember because you were too drunk
2) slowly remembering your drunk hook ups as the day progresses after you've been blacked out
1) Had deja slu last night with Rob, remember we hooked up in highschool?

2) Jane: Omg I totally have deja slu, I vaguely remember hooking up with Joe
