Just what in the hell does YMMV stand for ? I realize that the answer will make me go "Oh Shit, I should have known that"

orry, this had to do with Greek activities

When YMMV is used in reference to Greek activities many escorts will defer from activities if you're to big.  Also some providers will use your size as an excuse not to engage in Greek activities even your not that big and they have Greek available in their TER profile.
