Deck if said in the correct accent (aka a crewe-ite/ Dev-Vo accent)would usually sound like the word dick. It is also a way for you to say the word dick in front of parents with out any consequence, though if you do this you are in fact quite the loser.
It is also a name for someone who has very small knob.
