Top Definition
A substitute teacher who has no idea how to teach a class and always goes on rants. A Hubbard also brings up the most random ass things during english class and say the most ridiculous stuff (e.g. date of her husband's death, son is a personal trainer, had an abusive grandmother).
Friend: Dude, do you know who we have for a substitute for english?
Me: No clue but someone told me that she brought up that she had stage 3 breast cancer
Friend: Oh shit it must be a Hubbard.
