i too, enjoy munching on potatoes

A phrase used to say to another person in a polite manner, "Go screw off."

Tom: Hey Bob, did you see that new V2?
Bob: i too, enjoy munching on potatoes

sit on a ham sandwich with mustard!

Only used in the direst of situations, when an extremely rude person is relentlessly insulting you. It is both a powerful offense and defense.

Tommy:'Did you hear what Sarah told Bob? She told him to sit on a ham sandwich with mustard!'
Jessica:'What happened to him?'
Tommy:'His eyes rolled back in his head, his blood fizzed and boiled, and his spine slid out of his anus!'
