Loosely derived from "autocorrect," autoceleb is a person who gains mass appeal and gains many, many likes by reposting (thoughtlessly regenerating) memes that can be related to on a universal level, I.e., cats, goats, mustaches/beards.

Any person who has spent enough money on a car that he/she becomes unbearably prejudiced whenever conversing about cars.
