As you probably know, scottish slang is very weird and it depends on where abouts in Scotland you are from. Where I come from, these are the slang words:
I ken=I know
Okay, those were the obvious ones, I'll put down ones I know, but I don't know if they say them from where abouts you live.
Leg it=Run away
Sorry if I didn't give you the answers expected, but that's how they talk where I live.
Born and lived here my whole life ;')
