In cricket a Yorker is a ball that pitches at the batsmans feet. This is the most difficult ball to defend against. Joel Garner had an immense yorker and Waqar Younis and Wasin Akram used the principle of Reverse Swing to make their yorkers almost impossible to play.
Commentator: Got Him! He's gone, amazing yorker which beat the batsman all ends up and knocked his middle stump out of the ground!
The act of soiling ones self, under the influence of alcohol. The original 'Yorker' took place one night at university by a certain Mr York, who managed to dirty his bed after a particularly heavy night drinking black russians.
Oh god, i've yorked myself!
You dirty b*stard, you've yorked the bed!
I got so p*ssed last night, i did a yorker...
