Hooligan

There are several artists/group who share the name Hooligan. One of them is a Korean rock band.
Here is what Hooligan (훌리건) have to say about themselves on their official site: These aren’t the hooligans that go crazy over football.
No, these five guys simply share a common passion for music and their music is listed #1 on their crucial list. They don’t care what the world thinks of them nor do they give any concerns to how others might see them.
These people, they’re just a group of perhaps simple-minded and perhaps somewhat odd men who go crazy for music.
