Some hopping on Youtube lead me to parody artists Endo Jidai.
This is their cover-parody of SNSD Mr. Taxi.
They're dancing to Girl Generations' song with a more eloquent twist into it. What's more, some of them are guys and they're good at executing girl's moves! After looking at the video, the definition of dance cover and parody is challenged - what they did make it hard to classify into either, maybe half-half.
Check out their channel to view more of their SNSD parody.
