One of the few last names that, when spoken, is generally followed with a long, yelled SMYTHERRRRRRRRS! Someone standing behind you will ask why your friend yelled Smythers so loud and you'll have to explain that it is from the Simpsons, and various other places and end up more confused than you started. Such a great last name.

When some little bitchboy is acting like a little tiny pee pee poo poo baby and messing up the group plans.
