Someone who is a pathological, compulsive liar that likes to make shit up like shooting people's kneecaps off and smuggling drugs during the weekends. Whereas in reality, he's just a bald, choir boy who is insecure, probably because he has a strict mom.
Person A: I was talking to Peter last night saying he's gonna smuggle some drugs to Poland...
Person B: That such a Peter thing to say...
Person A: Yeah, that's before his mom told him to get off the computer...
