Hear that bass? It kicks and turns and curls up in your belly, makes you wanna freaky-deaky, right?

Our reading
An editorial interpretation.
Buck describes bass through movements felt inside the body rather than through sound alone. The question then links that physical sensation with an invitation to respond. The slang leaves the precise response open, so the passage need not be narrowed to dancing or any single activity.
