Basically like a regular high school party (drugs, alcohol, shit breaking, pissing off elderly neighbors), with the increased chance of sexual acts and favors. Participants sometimes compete for who can have the most sex at these sleepovers, sometimes in the living room if they're drunk enough. Do NOT tell ANYBODY what happens at a high school sleepover.
Yo I just went to a High School sleepover.
Chad says he got so much sex at the high school sleepover.
