A friend once said that my gf was แม่เสือ..I know mother tiger, but what would/does it mean to a Thai?

Sorry, im not able to help, but your question did get me curious as i had never heard that before.

I found this article: http://mgr.manager.co.th/China/ViewNews.aspx?NewsID=9540000011363
Other more knowledgeable members are sure to give you a more definate answer, but if this article is anything to go by is comes from a Chinese term meaning a pushy / strict mother.

i did go to google images first and showed women in tiger print looking sexy and i though "cougar" lol..and wondered if you gf is older than you. ..but im applying a western term to thai language, so i realise thats off.
Hope you get a better answer, im interested to know too.

Edit: Just found this too:

The full term is แม่เสือสาว. LaraC, you're actually correct in your assumption, it is very close to the English slang "cougar;" it means a [usually older] woman who has the ability to attract many men and get them to fall in love with her. See this article:
