That unique time of year when the college student puts the moves on their close friend of the opposite sex before summer break in order for a week long sex binge to occur. The week may be spent with the same partner or multiple partners but the goal is to get as much sex in as possible before the four month long summer kicks in where opportunity for sex isn't as easy as a walk across the dorm hallway.

Girl:"Yeah sure, make it quick though I gotta get as much sex in as possible."
Guy:"Best screw week ever."
