the jump on

Something that really sucks, is mega-lame, and/or blows goats Reno style. The opposite of the jump off, which means a really awesome thing or event.

Peter: "Wasn't Sean's party last weekend the jump off? I hear you hooked up with Veronica after that. Way to go. Soooo hot, want to touch the heinie."
Robbie: "Yeah the party was the jump off, but you know what's the jump on?"
Peter: "What?"
Robbie: "I think I got the clap!!! It itches. Also I've got some real nasty you know who."
Peter: "Ooooh...Dick Trickle? That's rough, chief. Totally NCAA."
Robbie: "Word to your mother."

jump on the fridge

A term referring to being so satisfied and contented, that you think you could die happy right then.
Originates from the story of a cat who was so happy with life, that it jumped on top of the fridge and died in peace.

"Nice work passing you're driving test man, you must be stoked!?"
"Dude I'm so happy I could just jump on the fridge!"

"That was the best sex I've ever had, I could jump on the fridge right now!"
