Why would you want to bring him back down to earth? Unless, of course, you have a passion for boring housemates?
Coolio is not intimidating. Plain as such. He is an overinflated character, a million miles away from being genuinly intimidating. Besides, no formal complaints of intimidaiton have been made because the housemates see past him also.
Kick Coolio out, and it is just another nail in the coffin.
