A dish of green peas which someone has, with or without permission, ejaculated onto. This most commonly occurs with mushy peas or pea soup, as the semen can be stirred in so the person eating the dish is unaware of the hidden ejaculate.
While this is generally a cruel and unhygienic practical joke, the eater often develops a taste and, later, even cravings for wankypeas. This can be troublesome for single women who then have to source extra semen to season their pea dishes.
It is considered a delicacy in Venice.
"Don't you think this pea soup tastes funny?"
"Yeah, when you went to the toilet, I spunked in it. Enjoy your wankypeas, loser!"
