n. The feeling one has after deliberately eating a meal at McDonalds or another fast food establishment despite the highly fattening content of such meals. Like McGuilt, McRegret occurs in persons who ate fast food but wish that they had not. However, persons experiencing McGuilt are concerned about the social ills of McDonalds as a corporation, while persons experiencing McRegret are simply concerned that they are getting fat.
I had a bad case of McRegret after breaking my diet with a Big Mac Combo and a sundae; I think I'm gonna fast tomorrow to make up for it.
