Dirty Lamb Chop means: A Dirty Lamb Chop refers to when someone makes a puppet with their hand and masturbates. It is more like a single man’s job. This term was inspired by the Lamb Chop sock puppet sheep. This can also be done with a puppet drawn on a sock that has a hole. Canadians, Eskimos and Santas Elves prefer the sock version. This can also be done with some peanut butter. (in Community Dictionary, added by Catalina Bernard)
