when partying, after the effects of your first dose of "whatever" are beginning to diminish, the attempt to maintain one's high by inhaling more substance(s).
Hey, I ain't tryin to go down just yet, lemme bump up a little.
Dude1: wow you guys are talking and carrying on like your all bumped up.
Dude2: yeah we scored an 8 ball at the bar and we've been doing bumps all afternoon
Dude1: You two are good at making piss poor decisions
