At my club there is this

who is so cocky and smug I hate him, he is the embodiment of
tfg. He plays tau wins almost all the time each time going strait to his ego, I'm sort of the one who runs the club so I kind of have the power to ban him, but because its a school club I cant tell him to

off.
Their are several really annoying things about him apart from his attitude;
He scared off a load of newbies who on their first game facing him, you can guess the rest.
He wont get a new rule book but just expects to get in the school league team I cant say no because hes so cutthroat he actually stands a chance(we faced 6th formers every time) but loses points for equipment.
His paintings fecies about 4 paints a model very sloppy due to his ego he thinks he's the best.
He cheats either on purpose or because he's lazy, his tau battle suits gave them maxed out upgrades and didn't pay the points because he "didn't see the points values next to the weapons".
When it come to cover saves that wire test tube rack is apparently 4+ and he wont listen to common sense.
Worst of all he hasn't played since July because he got 4 other people and two warhammer club members to sit at the back and play yu gi oh instead and I cant throw them out.
So to recap he's a obnoxious tw-- who needs taking down a peg or twenty.
So my question to you dakka is how ?
