An insulting work meaning an idiot or fool. Also means dirty, watery stale cum that looks like dirty whisky coloured slop. Usually ejected from an old man's wrinkly cock.
Examples: Fuck of your nobscotch your doing my head in now. Ooooh, what's all that stuff that's just come out of your cock, it looks like nobscotch.
