Bruce's version of participating in the dancing is a bit of bouncing arrhythmically on the balls of his feet while he keeps craning his neck to look at people.

He doesn't do clubs, but crowds can be very convenient for disappearing into. He could probably do it again without much trouble only there's Tony with an arm around his neck shouting nonsense at him that he assumes probably makes perfect sense to anyone who hasn't been eating all the wrong things.

Which is how Bruce ends up kissing Tony in the middle of a rave on a planet that almost no one on Earth has heard of outside of the Asgardian contingent. They really should get back to Earth before this gets much crazier.

Instead, when he comes up for air two seconds or an hour later, he isn't sure which, he shows Tony the blinking dot on his hand and shouts, "Want to see a show?"
