The best defense is a good offense, especially if some dude starts grinding on you. Remind any dance-floor barnacles that you can break a grown man's femur with one slick stomp. Or a bit of well-placed flailing - I'm not judging. You do you, bird.
PS: Don't forget your spiked combat boots for the dace floor. Emus would love to wear them, but they lack any appendage remotely resembling arms and hands with which to tie laces. Capitalize on those thumbs, dance commander.
