Is there a known culture for people like this?

well seeing as robbie williams doesn't apparently know what an emo person truely is....emo is some-what a culture. it is a genre of punk music (ie the get up kids, dashboard confessional, beele and sebastian, the starlight mints, etc.) and when you choose to live a "punk rock" lifestyle you may choose to be an emo kid. no that doesn't mean your f'd up or depressed. it simply means you listen to the emo style punk music and are a punk rock kid. and fyi emo music is generally the slower style music when you can actually make out the words, and robbie williams sure as hell isn't emo!
