Can anyone tell me... what`s a Harlem Shake? O.o

It's a really ランダム group dance where a group of people are 芝居 normal while one person starts dancing randomly. When the 音楽 changes everyone joins in.

I didn't know what it was at first too and everyone did... It's basically a dance to a some Hispanic song... It doesn't have any steps または moves it's just ランダム crazy shit! At first everything is normal people chilling and staff then someone starts to do something very random... Once "Do the Harlem shake" comes up EVERYONE starts doing something funny and random! Check them out their the new Gangdan style of YouTube! Military and underwater! Put H and the first thing that's gonna come up is Harlem shake. People do it ramdomly... Me and my local アニメ club did it :) It was fun

its a virse...

The best thing EVER

the Harlem Shake, my dear friend, is just ランダム dancing to a really ランダム song. But it has a good dancing beat. in my video these people are dancing and using 'The Bernie' as there ランダム dance movement. But really its anything あなた want. there are so many versions on youtbe ! many are super hilarious !!
