"Facebook poking a kid you danced with at Pulse for the whole night, even though you never talked before: Cute or Creepy ?"

Definitely cute. Most guys are too afraid to confront girls after something like pulse because they're afraid of being rejected. So facebook poking is the perfect thing to do to make a guy realize that you're interested. He'll be excited that you made the "first move" and guys love girls who take initiative. It's flirty, but to the point.

So yes, go ahead and poke him haha.
