A somewhat jocular and ironic insult somewhat similar to '
cocksucker'.
Most often directed at heterosexual male friends, it subtly and ironically implies that as the
target is clearly such a
bender, that being accused of cuntfuckery (i.e. heterosexual intercourse) will likely be considered an insult.
A: "Oi, you spilled my
drink. Watch what you'
re doing, you stupid cuntfucker!"
B: "What! How dare you call me that... Oh wait... You'
re right on both counts!"
