In my experience: The way I've encountered people using the word "teacup" is to brag that they have a tiny and how much money they have and that they can afford it. I live in a neighborhood where there are plenty of snobby, rich, spoiled brats (kids and adults). They use the term to talk down to me and Uni who is "standard" at 5 pounds, but all they are really doing is showing me their ignorance. They sometimes give a look of disgust and say "Wow, she's a big one!"

As for "teapot" it is a joke on the people that have "teacups", just to refer to their being larger than standard, but you don't hear breeders using that word, that's why I'm ok with it.
