I wouldn't say anything behind his back that I wouldn't say to his face...and do.
He's a plank, a tosser, an eejit, he has a scruffy beard, he talks monumental amounts of shite, he get on me tits, and he's a whimpering MOUSE.....and don't even go down the *** route.
Other than that I actually quite like him in a masochistic sort of manner.
