Oral sex technique involving a regular funnel. The cum swallower holds a funnel in his mouth in order to not spill any of the semen outside the oral cavity. Made popular by amateur pornstar Britney (aka Chicktrainer). Aside from the obvious degrading sexual aspect the technique is supposed to combine the appeal of both the visual (external) cumshot as well as semen swallowing without the usual problems of spillage (= facial moneyshot).
Britney got cum funnelled and swallowed every drop of semen.

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.
