Get the rug munchermug. 
An ethnic slur for someone of Irish nationality or descent. Derived from the time when the Irish ate potatoes during their famine.

Get the potato munchermug. Ex. 1.) Yeah, I know that anus muncher.
Ex. 2.) SON: Dad, you've told me a million times that drugs and alcohol are bad... believe me, I understand. There won't be anything illegal or dangerous going on at this party tonight. Just trust me.
FATHER: (sigh) Okay, son, I suppose it is time we let you start spending more time with your friends. But remember son, if you start drinking and doing drugs you'll end up an ass muncher, just like all those rappers you hear about in the news.
