I think I have found the origins of The Dab, and it ain't pretty. Dabbin' is supposed to be cool. Cam Newton is doing it, Frank Beamer is doing it (not well, I might add), even Urbs is doing it (*cringe*).
I am fairly certain that Ed Grimley started the Dab back in the 1980s. You be the judge.
Not cool, kids. Not cool.
