Tweegocentric is a word spawned from the popular social networking site, Twitter.
When a person is tweegocentric it means that they are so egocentric that they think they are by all means the most important person on Twitter. People like Justin Bieber and other celebrity douchebags are tweegocentric, because they think the only reason anyone goes on Twitter, is to follow them around like dogs.
Tom was being a Tweegocentric douche yesterday. He thinks just because he has 100 followers, that everyone loves him.
