Funneling is the act of a group of friends effectively getting a particular girl to disregard them and tell her what she wants to hear in order to "funnel" her to a certain other friend . The opposite of cock-blocking. Often associated with the term "wingman", this maneuver generally incorporates multiple wingmen acting as a single unit working towards the same ultimate objective; to get a buddy laid.
This maneuver is never to be used to funnel the DUFF to another buddy, but can be used to dump her on an unsuspecting douche bag.
