There's this game show in France where two contestants are both given the same set of letters, and whichever contestant can form the longest word out of those letters gets to score points.
The letters are drawn semi-randomly, with each contestant calling for a consonant or a vowel until the board is full, so it shouldn't be surprising that someone would end up forming an offensive word for the sake of winning.
But this one is pretty classic.
ENCULAGES is French for BUTTFUCKINGS.
You can see the hesitation in the guy's face before he says it out loud.
