All else aside, what the heck? Since when?
Note that your first two links both used different methods in their headlines (the TM and single quotes) to emphasis that they were not using this word, but reporting on it. And I think even something as simple as those quotes would have absolutely changed the tone of Grr’s post.
Mom is pretty oblivious, I don’t think she realizes it’s a ‘breastuarant.’
Of course we also have “boob-din[n]er” in there, which is not an industry term as best I can tell. Just an excuse to bring up boobs.
This seems to fall neatly into “shit I wouldn’t say at a dinner party in front of people I’d just meant.” Both words bring to mind nothing but dudes elbowing each other and giving not-so-sly winks. Breastaurant. Get it? 'Cause it’s a a restaurant with breasts?
And then some other guy chimes in with, “YEAH IT’S A BOOB-DINNER” and everyone gets uncomfortable because it’s not even clever. It’s just some guy who thinks he had an excuse to say BOOBS really loud. Probably the same guy who thinks it’s funny to ask women at bars whether they like great tits.
