An Apple computer user who takes any opportunity to advertise to the world they are 'better' than everyone else because they use a mac, even if this statement has nothing to do with the current conversation.

Mactard> HaHa Use a mac!! My mac is better than you're PC anyday! I am so cool because i have an iPod!
User 1> Anyone else? Anyone who isn't a mactard?
