look up any word, like dirty sanchez:
 
1.
a nicer, politer, and above all quicker way of telling someone, in that order, to "shut up, get lost, and mind their own business"
two people are in a private conversation and a third person butts in:

person 1 (adressing person 3): who exactly are you and what do you want? and why did you interrupt our conversation anyways?

person 2 (adressing person 3): yo man, sorry, but you are not part of this PC (private conversation). please eat your own cheese and shove off, before we get angry, all right?
