A bahooky or bahookie, is Scottish for one's backside/bottom/bum.
A typical Scottish mother would shout to her wayward child "I'll skelp (smack) yer bahookie if you don't stop that nonsense!"
A bahookie is a Scottish term for the backside.
What you should want to do right now is get yo lazy bahooky off the computer and loose some of that weight that's been growin on ya since your lover dumped ya! That's right I said it! I want to eat a CUPCAKE! (I love CUPCAKES!)
