To trumble, when a big girl (not just fat, big too) is being annoying and not really realizing she is big. Literally referring to the manner in which she moves: trumbling from place to place, but also just her general existence.
Julie came trumbling into class with lunch in hand again. She eats during class EVERY TIME!
