A French phrase indicating surprise, excitement, disappointment , distress or annoyance. A moderately strong reaction to something that was just said or done...
It's a French expression, but doesn't mean what you think it does
Oh la la! Un autre embouteillage?! Monchef va me foutre à la Porte si j'arrive en retard! (Oh god, another traffic jam?! My boss is going to sack me if I arrive late!)
