I would say, that since you have so many points for your captions, that you are most definitly "Mackin' on this contest". However, if you wish for this contest to be "mackin' on you" that's a really interesting thing to consider. You could be mackin' on something else, but this is CD and mackin' on CD is fun. One is never too old to be mackin' providing the put the appropriate amount of effort into the said action.
