A person who misconcieves usage of the word "punk", believing that it's conforming to pop-punk. After Bad Religion, The Dead Kennedys, The Ramones, etc. introduced and/or became a leading influence in punk rock, their philosiphy came to mean that people can basically do whatever they want (see anarchy). Today, these bands echo into modern groups such as Blink 182, NOFX, or AFI. Being popularly endorsed, Hot Topic material, they really contradict the whole idea of punk, earning the term, psuedo-punk.
Punk has an affiliation with emo, though Psuedopunk contradicts with psuedo Emo.
Punk - Being original, not like anyone else. Given that, it's close to impossible to put an affilliated definition onto it. Usually punk rock consists of fast-moving beats, such as heard in Crass, Subhumans, The Germs, X, X-Ray Spex, Dead Kennedys, Brother Inferior, Whorehouse of Representatives, The Ramones, Bikini Kill, Team Dresch, Bad Religion, Naked Aggression and Conflict.
Psuedopunk - Often offensive misconception of anarchy (people who believe it's disorder and chaos, rather than people not needing government), uses more hard beats than fast beats. Because most of this is commercialised beyond belief, such as in Hot Topic, and don't encurage originality but mirroring people (thousands of people wearing the same shirt, trying to be 'original' and 'catchy', but failling miserably).
