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).

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.

A swaffler can always be spoted because it attracts pink elefants. to keep safe from them, always carry a green mouse with you.
