Top Definition
A person who always does the "right thing", never does anything that they're "not supposed to do" and acts "perfect" in every single way possible. Usually a very peppy/happy person who is a "go getter". Also usually a girl. These people can be very annoying because of these traits.
Omg, that girl is such a goody two-shoes. I hate the way she acts like the teachers pet.
