Someone who doesn't dance and is trying their hardest to dance. They end up "about to break dance". Arms move toward the ground as if they are about do a big break dance move but it never happens. And everyone is left waiting for the big moment
Person 1: hey! Look that guy is gonna break dance! Let's give him space!
Person 2: nah! I've been watching him for 10 minutes, he's "about to break dance" it's never gonna happen dude!
