I'm no psychologist, but at a guess, I'm sure the 'skirt' comments can really be translated as:-

"I wish I had the style / courage / self belief to wear a kilt too. However I don't have, so I'll try to put down anyone else who has. After all if I can't do it, why should he ?

Oh, and I'm a bit of a saddo as well, so I'll only comment if my buddies can hear it so we can all be pathetic together....."

Twenty years ago, these types would probably have been making similar distancing 'macho' style comments about deodorant or having a shower more than once a month...

If only their self confidence matched the size of their mouths....
