RoccoGiovanni saidThe first one is pure sissy!
The first one captures the spirit of the song. This is obviously a song meant for ass-shaking, so my vote's with the first guy. He does show off a variety of ass-shaking methods from a good variety of positions, while commanding the space around him. Well done. Although he does have poor form in some instances, as mentioned earlier, he overall did quite well.
The second guy completely misses the mark. This is not a choreograph-dance song type, and his choreography is mediocre at best. He does have great form and displays some very skillful moves, but the overall product is sub-par. He also uses the space well, and that's good too, but he fails to use either the lyrics or the music to carry his movements.
