wan can dan
Scottish way of saying, “you get drunk off of one can/glass/bottle…etc” or “You’re a lightweight”. So, if you happen to be a ‘wan can dan’, prepare to be slagged off. lol. I actually happen to be one, so you’re not alone.
“Haha! You’ve only had one can of that dragon soop n yer awready oot yer nut. You’re a pure *wan can dan*.”
