Too right! Hell, when I was doing my teacher training, I once overheard a couple of students discussing something of no particular interest to me - who was going to supervise them during their spare period, or some such.
"Yeah, it's Miss Hudson"
"Who?"
"You know - the one with the plastic face"
"Oh her. Right"
I nearly had the sort of accident in my trousers I hadn't experienced since I was at kindergarten! I managed to keep on staring out the window and keep a poker face somehow. I was only a student doing teaching rounds so I was wasn't familiar with the names of more than a half-dozen staff members, but the moment that Year 8 kid said "the plastic face" I knew exactly who they meant.
So far as I know, she had a perfectly normal complexion; apparently she just didn't feel dressed with less than half a pound of assorted powder, lipstick, blusher, eyeliner, foundation, eyeshadow, and for all I know pre-stressed concrete on her face.
Pity I don't have her address, I could send her some appropriately over-processed landscape photographs. I'm sure she would love them.
