Have you ever seen someone with a Glasgow/Chelsea smile?

I think it started in Glasgow, but it's probably better known as a 'Chelsea smile'.

I lived in Glasgow for a few years in the 80s, but I honestly can't remember seeing anyone with a 'Glasgow smile' back then.

However, last time I was in Glasgow, I saw two different blokes with Glasgow smiles. Not the nicest of fashions. It's a sick old world.
