Descriptive term for an incredibly arrogant & egotistical man who has considerably over-achieved in their life for no apparent reason. Often a tradesman or a footballer, a massive champ is easily distinguishable by his clothes: collared up shirt, truckies hat, white shoes & yellow wristband.
That chick at the bar is incredibily good looking, but have a look at the massive champ who is having a crack her. That man is an outrage.
