vive la différence

Etymology
Borrowed from, literally “long live the difference”, from +  +. Although correct and unremarkable French, it is not a stock phrase in French as it is in English.

Usage notes

 * Often used as a humorous exclamation (e.g., by a man appreciating an attractive woman).
 * The term la différence is sometimes abstracted from this saying to refer to the difference between the sexes, or to heterosexual sexual interest implied to result from this.
