More About Chicken Head
The term is generally used to describe women who give oral sex, or a lot of oral sex. It is sometimes, though, used to describe homosexual men who perform the act of fellatio. The term describes the movement that the head makes during fellatio, which is similar to the movement of the heads of chickens because as they walk, they bob their heads.
