You get it? It's because a turducken is a turkey stuffed with a duck stuffed with a chicken, and this girl's mouth is similarly stuffed with cock. We added the "en" on the end so this would make sense.
With apologies to the person who titled this video, we don't believe that her mouth is quite stuffed. We've seen such things happen, and the cheeks looks way different. (This is like our equivalent of "This looks shopped; I can tell from some of the pixels and having seen quite a few shops in my day.") On another note, we really appreciate the way our cameraman uses the bathroom mirror to establish the scene.
