Dab (dance)
dance move popular online (allegedly originally a synonym for swag) / From Wikipedia, the free encyclopedia
Dabbing, or the dab, is a simple dance move in which a person drops their head into their bent upwardly angled arm, while raising the opposite arm out straight in a parallel direction.
Since 2015, dabbing has been used as a playful manner, becoming a youthful fad and Internet meme.
The move looks like someone sneezing into their elbow.[1]
