Skanking seems best when listening to traditional ska, like The Skatalites. It's mostly the bending of the knees to the offbeat and doing something goofy with the hands. Sometimes it looks like the twist, or like you're juggling invisible items, or like you're pulling on a rope with both hands, but it's fun and nobody around you cares because they look sort of goofy too.

Third wave skank is actually a kind of retarded, mutated version of old skank, and since lots of third wave ska is fast and punk influenced, it looks spastic and weird. then again, lots of third wave bands like the articles and the New York ska-jazz ensemble are nice to skank to like the Skatalites are, too.
