To jump the party is to have sex with more than one person at a time usually when everybody is fucking wasted.
Matt: When she asked me if I wanted to have sex I had no idea she meant jump the party with her whole sorority!
Steve: Dude, you should have invited me.
Matt: Hell no! If I'd have seen you naked my simon would have went limp.
