Backstory, for those who might be interested: a friend of mine posted some good news, and another friend commented on that post with "WOOT!" - only later she felt she needed to clarify a bit...because her icon at the time was St. Therese of Liseux, and the thought of the Little Flower going "WOOT!" was a bit...funny...to her.
Myself, I find it anywhere between incongruous and downright hilarious, but then I'm firmly convinced everyone in Heaven has a much better sense of humour than any of us do anyway ;)
So. You're a Francophone (either modern-day or in a 19thC Carmel). Something cool happens. A bolshy English speaker would say "WOOT!" Vous dites........?
