In the fifties it was the Teddy Boys, in the sixties it was mods and rockers, the seventies saw punk and the eighties had new romantics. Now, in the noughties, we have hoodies.
As ever with teenage "fashion", Nanny is scared sh****ss.
Nanny ignores that fact that as with all teenage "fashion" it will pass, and that it is worn merely a sign of fear of not belonging to a group rather than as a sign of criminal intent.
Anyhoo, notwithstanding that, Nanny recently decided that Jack Johnson was inappropriately dressed when he went to his local shopping centre in Eastleigh.
He was wearing the dreaded hoodie.
The reaction from Nanny?
Nanny's security guard banned him from wearing the hoodie, or leave, in case people were scared.
Jack is only six years old, and the hood was part of an attachment to his school coat.
What about duffel coats?
They have hoods too.
Jack's mum, Tracey, said:
"I couldn't believe it.
It wasn't even a hooded top but his school-issue coat."
This man was going to kick us out unless Jack took his hood off.
Just how scary does a six-year-old look in his school coat?"
"I thought it was silly and I was sad and upset."
Nanny is silly, and very upsetting to many people.
