Well, scientists can be the judge of that.
British researchers put on some German music and asked some men to dance. The scientists put sensors on the dancers' heads to keep track of their movement and converted the movements into an animation on a computer.
Women were asked to rate the dance skills of these avatars — so that their physical attractiveness did not matter and perhaps to ensure the bad dancers didn't end up going viral on YouTube.
The scientists said good dancers make variable movements and move their torso and head a lot.
What's more, blood tests suggest that the better dancers are healthier.
BBC correspondent Pallab Ghosh said assessing someone's dance moves might be the best way to judge a mate.
I was recently in London and saw this type of bad dancing at the clubs there.
The lesson here? Guys trying to pick up girls can be more successful if they learn the right dance moves. Just watch and you'll see why some dance moves are sexier than others.
But wait, let's not get ahead of ourselves. Will Brown, a psychologist at the University of East London, told The Guardian:
"When you have so much movement data from a relatively small sample of dancers, you might get chance associations between certain moves and dance attractiveness," he said.
"Flexing the trunk while dancing may be attractive, but we need to show it is indicative of a better quality male using an independent measure of biological quality."
