a lick given immediately after a dog has dined upon feces, or licked b-hole. It is the dirty sanchez variant delivered via dog tongue, that is not necessarily centric to the upper lip.
It was only when I noticed a smear of shit on my wrist that I was able to concede that my face, which had also been licked by my dog, was also covered in shit. My little puppy had executed a very thorough D. Tongue Sanchez.
