All I’m gonna say is this: You probably saw how long the Hal Briston and the sheep thing was an active running joke, and that wasn’t even something he said.
Part of the problem is that, since this is potentially the least spontanous form of communication available, anything you communicate is going to be treated as though you thought through the implications.
Part of it is that many people are going to say “how can she be offended by us repeating something she herself said–if she didn’t want us to talk about her awesome boobs, it was her choice to not put that phrasing out there.” A subset of these people (the ones with drool bibs) will tie it back to your user name being that of the underage porn star (I know the difference, so you don’t need to correct me. =P)
Part of it is that you react predictably and negatively when poked by it, and there are people who can’t resist that kind of temptation (this is far more likely to be the real reason why people do it than sexism–it’s got nothing to do the fact it’s boobs and everything to do with your reaction (see also “buckeyes”)).
Hijack done, but just wanted to give you that advice before you continued to shoot yourself in the foot. I recommend one warning per person that you don’t appreciate it and then liberal use of the ignore feature, assuming you find it utterly impossible to follow StGermain’s advice to just let it roll off.
