How do you say "cougar" in French?

From Urban Dictionary: Cougar (n.) (see also MILF) - an older woman, dressed as a younger woman, who likes to seek out and conquer younger men. She can quite frequently be found in professional settings though her habitat of choice tends to be the bar. Example: "I'm dating a nice guy, unfortunatley he's surrounded by cougars older than my mom...."
