DANCE, DANCE REVELATION
Bump and grind
What it looks like is he's giving a lap dance from behind. What it means is he's passionate and comfortable with his sexuality, but he also may consider his own desires before yours like whether you want to have to have him grinding against you.
What it looks like is he's jobbing in place, a la MC Hammer. What it means is he is laid back and does not take himself too seriously. And while he'll make you laugh, he also uses humor as a defense mechanism, suggesting he is not totally at ease opening up to new people.
Faux breaking dance
What it looks like is he's a reject from America's Best Dance Crew. What it means is he's an attention whore, and his cockiness is mildly annoying. But his attitude also indicates he is spontaneous and willing to put himself out there.
What it looks like is he is awkwardly swaying, hopelessly offbeat. What it means is he's restrained and kinda boring, but the fact that he is not all up in other people's space shows he's thoughtful and sensitive too.
