Corpy means: A person who has a basic understanding but isn’t unique. Someone who copies and steals jokes, words, etc. from others. Because they are unable to come up with something unique, they often copy other people’s work and pretend they have it. Most likely, you will be able to tell when someone steals your jokeswords if you use them first and then have another person do it after you. (in Community Dictionary, added by Pierre Gibson)
