Jef is basically the opposite/flip version of Skeppy himself and is 'best friends' with Goodboyhalo, who is the complete opposite of the nice Badboyhalo. Jef doesn't swear and has the personality of Badboyhalo, the person who's nice on one half but serious on the other half. He's easily scared/frightened by Goodboyhalo 'pranks' that seems extreme to Jef. Goodboyhalo is often mean to Jef, who doesn't really seem to mind him.
