SF, I feel for ya man. It's referred to as Seattle-ASS by some. The office I'm contracting in right now has the same affliction running rampant. I would say close to 75% of the girl ass in my office is worse than your 'meh' girl ass.
The last time one of the fat asses in my office tried to tell me that I was too skinny I just told her that a lot of fat people say that to me. She doesn't say much of anything to me anymore.

She's rude in more ways than one so don't feel sorry for her. I could rant for days about how she tries to take credit for my work.
I don't personally have a problem with people who are overweight. If they ask a question because they sincerely want to know what they can start doing to improve their health then I'm more than willing to help. When they walk up with their family sized bag of Cool Ranch Doritos and laugh at the cottage cheese that I'm eating they're just asking for a rude response.
Too over the top? Not in my world.
