Get the French Arm mug.
The phenomena of transferring a foul smell from the lower regions (balls, thighs and/ or ass sweat) to ones forearm during the act of wiping. AKA- Arab Wristwatch, Turkish Glove, or Cleavland Handshake.
As John leaned forward and shook my hand I could smell a foul stench- he had a French Arm!
