Would you consider this "Normal"?

You guys skipped the game but kept the hat?

Yeah, bad teeth and bad attire in the UK is definitely normal! LOL

In algeria we call them the unemployed

Squatting Slavs in tracksuits

Truly understanding perspectives, you then know everyone is their own subculture.

There really is nothing that can be considered normal. Averaging can not express the vast diversity.

Which is greater? The point at the highest point of the curve, or the combined sum on either side of the highest point?

And this supposes that the highest point is truly normal, when everything is constantly changing.

Depends on your definition of "normal."

I'm guessing by "normal" you mean the most prevalent youth culture?
But what would you call it? If UK, maybe "Chav", but that's derogatory.
(If i saw this, id think: Fake sporty, possibly out of work, not-working class?)
Is it associated with a particular type of music?

No idea what that is.
