Something that I find really blood stupid is the stupid peroxide streak every teenage boy who thinks hes street has. Its probably an Australian thing but they wear really bright shirts (hot pink, light purples, pale blue) and then walk around like it doesnt make them look like they want to shag the bloke walking next to them.
The first time I saw one of them with the random peroxide streak, I thought there was some peroxide monster on the loose jizzing in teenage boy's hair.
(Though there is a bonus, working at a department store, it makes it easier to spot the ones who will try and shoplift or just be a dick to staff)
Edit: Yep, not a fan of emos either.
