The source of the embarrassment stems from an e-mail (yep, one of those again) that was sent by the lass to her beau and, inadvertently, also another bunch of people when she hit "reply to all".
For the few of you who may have missed the missive, here are some choice excerpts: "I have to write a sucky 'thank you' e-mail to clients now, w*nk w*nk. Speaking of w*nking - how was yours? Wish I could have been there to watch. You have made me c*m a few times, not as good as the real thing but I guess we have to make do the best we can with what we've got."
Then again, it could be perfectly innocent and they were discussing an unknown link between winking and cause-related marketing.
