Dab (dance)
Dab, or dabbing, is a gesture in which a person leans forward into the bent crook of a slanted, upward angled arm, while raising the opposite arm out straight in a parallel direction. It appears to be similar to someone sneezing or coughing into an elbow. Since 2015, dabbing has been used as a gesture of triumph or playfulness, becoming a youthful fad and Internet meme.
