A chillaxed hand movement where your wrist moves back and forth, similar to a blade of grass in the ocean. It takes a certain skill to master the seaweed. It's useful for choreographing and spicing up dances, regardless of the style or genre of music. The seaweed is versatile, it fits in anywhere.
Betty: Geez...I'm stumped choreographing this dance....what step should I put in next?
Don: Well that's a no brainer....the Seaweed....DUH!
