Dudes on this thread are being histrionic, like, if I can't call a woman a MILF at work, what's next, the PC gestapo are going to prevent me from making eye contact with women.
I can't stress this enough: if not being able to call a woman a MILF in your day to day life is an imposition, you really need to reevaluate how you talk to (and think about) women. I'll skip the moral appeal and go straight to self interest: on average, women just don't like that shit. You catch more flies with honey than you do unwelcome, overly sexually aggressive comments.
2It's a work environment, not a bar. No one should normally need to make a "first move" in this context. Sure, work romances do sometimes happen, but I don't think our population is in any danger if they do not.
A quick google suggests that 38% of people have dated a co-worker.
Edit: Actually we've banned this account for trolling.
There you have it. I'd bet dollar to doughnuts that if this person had simply "expressed interest," I don't think there would have been an issue. But if a total stranger says they only want to "hang out" as friends, and your reaction is to call them a MILF and try to share some creepy "secret" with them, that's clearly an unwanted interaction.
If you can't see why, I think quite a few people are very happy you don't have plans for management.
