Not be confused with Lefty Ginger. This sex act has been performed in the Washington D.C. area for over 15 years. It usually involves one deaf female and one hearing (and hairy) male. During foreplay the deaf partner roles over the other participant and goes to town on the ass. There is also considerable and distinct moaning from both partners.
"My roommate Lefty hooked up with that deaf girl the other night. I knew she was performing Silencio Chocolata again because the seal-like moans are a tell tell sign of ass eating by a deaf girl. It was filthy and I had to leave the house and take a walk around the block."
