A dirty Sanchez given in either a bathroom or kitchen area at a MacDonald's restaurant.
"Dude, as I ordered my Big Mac, I saw Ronald MacDonald give the night manger a Pounder McSanchez in the kitchen."

"I heard that George will let you give him a Pounder McSanchez for 20 George Washingtons if you catch him between chicken nugget deep-fry loads during the night shift."
Get the Pounder McSanchez mug.
