When an otherwise straight male is persuaded to, or on a whim in the heat of the moment, engages in a homosexual act of which he later regrets and is ashamed.
Alluded to in the musical number of the same name in Mel Brooks' film "Blazing Saddles".
Having shared the intamacy of a small tent for so long, in the stress of jungle combat, Pierre and Gustav came close to making the French Mistake on many a steamy night.

Get the French Mistake mug.

Throw out your hands
Stick out your tush
Hands on your hips
Give 'em a push
You'll be surprised
You're doing the French Mistake!

Occurs when a male receives oral pleasure and vomits on the lady or gentleman as he orgasms.

1. the french mistake is basicly the biggest mistake ever and now that country sucks. The mistake would be Napoleon a good strategist but also fucking retarded for sending 400,000 troops to russia to freeze their asses of while France was left unprotected.
Napoleon: I've done pretty well so why not send 400,000 people to Russia anyways I'm doing pretty good right now so nothing could go wrong. In the future this decision will be called the french mistake.

the English: Wow i actually feel kind of bad we didn't win this war Napoleon basicly handed it to us :). Thanks anyways guy.
