A British phrase used when a young lad masturbates and ejaculates into his hand, and tosses it into someone else's face.

Usually an insult, but can be used as a sign of affection on the oddest of people.
"Mrs. Steger," the lad says to their Latin teacher, "have you ever been spilly winkled?"

"You want to spilly winkle Her Majesty the Queen? Treason!"
