A spinner is an exceptionally petite gal, so called because she is able to literally spin around while riding your cock in the cowgirl position.  (That's where she is crouching down on top of your cock while you lay flat on your back.)

YMMV means "Your mileage may vary.", and that refers to certain menu items that a gal might do for one guy, but not another depending on circumstances.  For example, a gal might do anal with a guy whose cock isn't too large and refuse it to another who has a much larger package.

A good source for all these things is the Urban Dictionary that you can access on line.

There is also a glossary of acronyms in the Self Help Center on here.

What terms or meaning of  
Spinners
Green
Ymmv

green could refer to money, as in "greenbacks", or it could mean "new and inexperienced". Normally it's the latter of the two.

read the Self-Help Center.  See the red and white life preserver at the top of this board.  Also, read several pages on your regional board and don't forget to post 1 ad per week on your regional ad board.

green could be anything.  The traditional meaning is someone or something new to whatever.  If there is another meaning, I have no knowledge of it.

Of course, in that case, it would be outercourse.

I was hoping to find out what a spinner was. My kind of girl.
