sœur

n. f.

1. 'Bird', 'lass', woman (usually a pretty one, the only exception being in the plural where disparaging generalizations are uttered. Les sœurs, c'est toujours pareil! Well, you know what women are like!).

2. 'Pansy', 'nancy-boy', effeminate homosexual.

3. Et ta sœur?! (iron.): What's it to do with you?! — Is it any of your business?! (This near-nonsensical repartee is sometimes followed by the rhyming and even more nonsensical Elle bat le beurre!)
