(Family Guy s5)
It has no real meaning, but chances are, if it ever becomes part of the standard U.S. vernacular, no one will be allowed to use it on regular television shows.
1. The coagulated substance clinging to the bristly groin of a female who has done without washing or hygene for at least a few menstrual cycles. An inch or two layer of sour cervical tissue creating a plug of greasy steaming filth in and around the entrance to ones stench trench. Often resembling a brownish green scab with black wire protruding from it in appearance, but harbouring the acrid smell of hot cheese and rotting prawn cocktail.
Most well known for the permanent dark stain it leaves on anything unfortunate enough to come into contact with its hot moist surface.
Often used by idiots and other people who can't form a proper insult. However if used well it can become quite humorous.
In essence it is an ambiguous swear word that is hard to define with a singular definition.
Tim: I am not, I quite like girls.
Bob: Well how come you've never had a girlfriend, and seem to not react to hot girls?
Tim: .... Shutup you.... clemin.
Bob: Oh very good you dirty little retard.
