Few years late to reply I guess, but he says "...in'd Hoar schmiern", meaning you can "rub it in your hair", which is a way to say that something is worthless (of sorts). Bit rude in a way when he said it, but Bavarian sometimes can be a bit rough around the edges. He didn't say ass or anything like that.
