J. Edgar Allen's definitions
An alternate term for a cleft chin because when cum dribbles out of a woman/man's mouth it naturally acts a funnel, guiding the cum down the center of their chin to their chest.
I got a BJ from toothless Tammy last night, she couldn't take the whole load so it dribbled down her cum funnel and on to her tits.
