The former "Two And A Half Men" actor has managed to change "sheenie" from a reprehensible ethnic slur to an adjective: "Have you been drinking? You seem really out of control, almost sheenie."
It's a kind of progress.
Update: Other possibilities: "He has the sheen of madness," or a twist on the old term for over-acting, "Chewing up the sheenery."
