I have an idea - from what i know Parrots copy what you say in passing. Maybe teach him one word but do not make him aware you are trying to get him to say it. So like while you walking by him pretend your talking to someone and say - "Bwin" use the word in sentences - like Bwin sucks, and stuff like that in pasing by him - haha - If he learns the one word Bwin - maybe later on he will add his favorite word in front of it or after.
FY Bwin or Bwin FY -- that would be classic - i would upload it to youtube and get it go viral - haha
