One of those guys who is sweet to his girlfriend, but still witty and manly. Not the white-as-snow knight in shining armor type, but a more byronic type of man. Derives from the best character on the TV show Dawson's Creek.
Pacey is a retarded person with the ability to flem on other individuals around him. He has big fat abs and a little willy. If you ever talk to a Pacey he will most likely throw a ball at your head and assume you’re austic.
