A person from Edinburgh, Scotland which is called Embra in the local dialect
All reekies are chookies but not all chookies are reekies.
Prince Philip is the Chooky Embra.
The art of leaving a social event in the midst of fun and games, and be dragged home by the testicles that your girlfriend has a firm grip of, then to say you shall be back in 1 hour precisely, only to never turn up at all.
"To do a chooky"
Chooky - "Back in an hour guys"
1 hour later...
Azmoden - "Where the f#$k is chooky?"
