Who or what is Wee Beasty?
I met a few small ugly Jock squaddies who were nick-named 'Wee Beasty'.
I think it's a standard nick-name for Scottish people who are short and ugly. A bit like anyone whose surname is Bell gets called 'Dinger', or White and called 'Chalky', or Clarke and called 'Nobby'.
If you're short, ugly and Scottish, you're called Wee Beastie.
Most of blokes in Scotland must have this nick name.
