Mucks (prop muck)
MUCKS, BREAK-OFFS, COOLERS & MORE - chapter 7, page 512
In response to one reader with an impressive memory, yes, I have demonstrated this move on television. The show was called A Current Affair and the excerpt from the show is included following the clip. The goal is to muck quickly, then use a prop (eye glasses, drink, napkin, etc.) to stall for a second or two before apparently picking up the dealt cards for the first time as the dealer gets to the mucker's position. Note: I'm obviously pretending to pick up a prop.
