The phrase 'head's up' can mean a verity of things. Such as at a ball game of any kind it means the ball is in the air so look up as not to be caught off guard. In this case however it means something entirely different. "Head's Up" as is expressed means your head is "up" in a good place enjoying the ride as everyone should after a bowl from a 'ROOR'.
