1. Week-long celebration of panhellenic fraternities and sororities at American universities and colleges. Students participate in a litany of meaningless events that the rest of the campus cares nothing about - capitulated by "skits" being preformed. Usually characterized by "frat row" or another Greek-populated area of campus resembling that of a frat boy and sorostitute minefield.
"Hey man, you hear the Sigmas are coming back!"
"No one fucking cares about Greek Week."
