running man challenge 

A dance with the song, 'Ghost Town DJ's - My Boo' playing where one commonly places their left foot behind the right and steps rapidly in place with other random dances placed in between. (spinning, bopping (the leg thing not whatever the fuck that other shit is), etc.) Fun to do with your friends and switch off to show off or just have fun.

Friend 1: Dude, the school is holding a dance but there's gonna be teachers crawling all over the place.
Friend 2: Doesn't matter, we'll still have fun.
Friend 1: Huh?
Friend 2: Running man challenge?
Friend 1: Hell yes.

running man challenge 

A new, hip, cool, dank dance trend on social media. The Running Man Challenge is when you are doing the "Running Man" to an old 90's song, "Ghost Town DJs - My Boo".

I wanna try that Running Man Challenge thing everyone's been doing.
