to hit something or someone with a half-erected (very important!) penis. the word was invented in Belgium - in the Flemish part of the country, where a variaton of Dutch is spoken. And yes, they're very proud of it.

Get the Swaffle mug.
The act of slapping something with a semi-erect penis. It's derived from the Dutch verb "swaffelen".

In 2008 it won the title "Dutch word of the year" in a yearly held competion where the Dutch speaking public can vote online which new word, that originated in that year, they liked the most.
It had gotten a lot of media attention because a Dutch student "swaffled" the Taj Mahal on a school trip; and got expelled from his school for that action.

Recently Brittish carshow host Jeremy Clarkson mentioned it in a talkshow (BBC Qi), where he gave the definition: "To bang your penis against the Taj Mahal".

He also mentioned the word on the fifth episode of the new carshow "The Grand Tour" which was hosted from a tent in Rotterdam (the Netherlands).
The Dutch boy that boasted about swaffling the Taj Mahal on his school trip got expelled from his school.

Get the Swaffle mug.
Active verb, refers to the practice of two sexual partners (generally overweight homosexual men, although heterosexual overweight partners can swaffle in rare instances such as anal or pegging) using desert-based condiments, such as whipped cream or syrup as a lubricant. The etymology of the word comes from the resemblance of the jiggling excess flesh, smothered in creams and syrup, to two swedish waffles on a plate. In this respect, 'swaffle' can be said to be a contraction of 'swedish waffle', although its uncontracted form is seldom used.
"I have maple syrup and some whipped cream, do you want to swaffle tonight?"
