right hand shuffle
A hand gesture meaning something similar to "What's up?"--performed by fully extending the right hand, turning the palm towards the face, and shaking the hand up and down, as if you were trying to get somebody's (who has spaced out) attention.
"Ey boy, don't be gon givin' me no right hand shuffle like you mie homeboy uh sumthin!"
