Wow... So many of these people. Basically, since being alternative is cool these days, people (especially young teenagers) have started to become wannabe rockers. There a few points to identify these people:
1. Listen to stuff such as Blink 182, or even Busted and McFly, and show off about it like it's so cool and makes them so special.
2. Vanadalises their school bag and sticks loads of mini badges on it.
3. Wears loads of colourful plastic jewellery.
4. Tends to wear black and then a very bright colour clothing.
They do it to be "cool" and it's not amusing.
Anyone who follows all of the above points.
