When you jump and then nut to jump higher
Similar to double jumping in Mario but you nut instead
Kid 1: yo our ball is stuck up on the roof
Kid 2: I got got you all I have to do is double jump nut
Another way of saying "Blue Balls".
When you try to get with a girl, but instead she gives you blue balls.
Resulting in your sperm jumping around needing to be released soon.
Man, Becky be giving me the nut jumps! If I don't jerk off in her face soon, my balls will explode!
