Better than good

Every day during dinner, we ask John about his day.  All week he has been giving his day a double thumbs up.  Today, I asked John about his day.  He smiled, gave me two thumbs up and said "Booyakasha!"  He explained to me, "Booyakasha is better than good.  A Booyakasha with two thumbs up is better than anything!"  I asked him, "How was the pizza at school today?"  Again, he grinned at me.  But he said "Booyakasha, Booyakasha!" And gave me two thumbs up.  He explained "Booyakasha is better than good.  A Booyakasha with two thumbs up is better than anything.  Two Booyakashas and two thumbs up is better than that!"

Of course all I could think of was the commercial below...
