The Profanisaurus - NSFW sorta.

[britspin]

I thought Yankee OOTs might appreciate the genius of the profanisaurus.

One definition I thought might prove particularly useful is:

U.T.B.N.B. abbr. Up The Bum No Babies. A reliable, yet illegal contraceptive device; opposite of an I.U.D.

At last - I will no longer have to explain stuff like 'flob up at the end of the vinegar strokes' to the Yanks anymore.

I think I also like...

cough your filthy yoghurt v. A romantic expression for ejaculation. A money shot (qv). "Ursula was powerless to resist. His eyes burned into hers like sapphires. His strong arms enfolded her tender body as she felt herself being swept away in a whirlwind of passion. Then he dropped his trollies and coughed his filthy yoghurt". (from 'The Gentleman and the Lady', by Catherine Cookson).

Or, if you like it more direct, 'spray the sticky white love piss' is fine and is more internationalist (ie less in need of translation), I'd say.
