A pewbie is a fan of Pewdiepie
that thinks every other let's-play videos of games he had played are copied and unoriginal. Pewbies go around youtube ranting about how videos copied Pewdiepie and flags the video for copyright infringing even though Pewdiepie doesn't own any game. Pewbies are what make most of the Pewdiepie fan-base.
