Ya'll come up here to the front 40, I need to show you something.

Anything awesome.

Front Dogging

Playing a cricket shot on the front foot, usually seen as disrespectful to the bowler as if the batsman were saying, "this ball is so shit it's no danger to me and I can just smash it down the ground, that's what I think of you fucking scum"
