Known Shitter

Someone who is a well-known/relevant member within a community due to their unfathomably egotistical personality. They will oftentimes have large egos but lack any sort of self-esteem. They also display a desperate craving for validation from their peers because they are physically incapable of having their own sense of self-worth.

Ever since that known shitter won the Fortnite World Cup, he hasn't shut up about it. He needs to go get some bitches or something.
