To Dance. To feel the music, and convincingly move to it like you know what you're doing. To dance in a manner that is appropriate for the music you are dancing to. To get locked in to the music, and move to it in whatever way comes up naturally. To dance with confidence, like no one is watching. To dance in a manner that impresses the chicks, and might get you laid.
"He couldn't cop a groove to save his life" - From the song "Poor Tarzan" by Little Charlie And The Nightcats ~1986
