I think you mean he's missing his sporran. (Gaelic for "ball protector," according to my Scots dad.)
So, girls can dress like low-rent hoochie-mamas, but a gentleman of Scots descent can't wear his cultural birthright?
The sporran actually serves as a wallet, holder of keys etc. - there being no pockets in a proper kilt.
However, as a friend of mine observed - if you get mugged you might actually enjoy it!
