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.

Shekel Grabber

Someone who does petty theft or small-scale scams for almost no profit in return.

That dude is such a shekel grabber. He said he'd pay my $0.50 back today, but he just ghosted me instead.
