The fleshy excrescence that grows under the throat of a cock or turkey, or a like substance on a fish.
I heard recently that celebrities (young stars and starlets in particular) are instructed by their handlers on how to handle themselves if/when they get arrested and have a mugshot taken. The protocol for celebrity mugshot deportment calls for the celeb to look down, and to do so demonstrably, so as to hide the fleshy excresence that many humans have in the space between their chin and throat.
