(Dee-rih-shush) Funny accented way of saying "delicious" usually used when something is beyond the normal form of delicious. Also used when the person making the description is a super-awesome intellectual person.
When a person of interest has something more than just a great butt. Also considered a high-level term of endearment. Usually best executed when prefaced with a grunt or similar sound when a man is presented with a plateful of bacon.
