It started picking up steam a few weeks ago when a couple guys from the University of Maryland basketball team filmed themselves doing this weird dance move, then a bunch of other college basketball players were doing it, and a few days ago it made the jump to NBA when Miami Heat's Justice Winslow made a video of him and his sister doing the challenge, and now TONS of other people have started doing it and it's officially a trend.
