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

When an alcoholic male decides that while he drinks he likes to accomplish other tasks such as watching porn, facebooking females and blasting music. This 230 lb male will set up shop with three computers and two 24-packs of Keystone Light. The first computer is for porn and thus is placed directly in front of the male, the second computer, which is to his right, is for facebook and the third computer, which is to his left, is for music (most likely Lady Gaga mixed in with 3 straight power hours).
Note: this event takes place in the RA's room and once completed a pizza delivery (the act of stciking for dick into a pizza box and opening up the flop once the customer answers the door) occurs at the neighboring dorms.
