Ten pinter or whatever comes before ten, E.G. an eight pinter or six or five pinter. Is used to decribe how many pints of beer you would need to drink to have sex with a woman. If she,s really monsterous and hugely fat and nasty then she would probably qualify for being a ten pinter. A five pinter might be just plain with goofy teeth and a double chin or saggy tits and amaciated legs.
Fucking hell mate, look a that ugly fat slob of lard. She,s a ten pinter ( ten pints of beer) i reckon.
