George W. Bush, also known as the president of the United States of America.

The act of extreme masturbation. You must "knock one out" whilst in close proximity to any of the following; Your mum, a nun, your boss, a member of parliament, George Michael. A person with capabilities to act upon catching you mid self-abuse obvisouly ups the ante. Ejaculation must be reached before your danger wank target comes (no pun intended) to investigate. The higher the chances of being discovered with one's pants down, pulling one's war face is obviously where the danger comes from. The more danger involved the harder (or softer) it is to complete the task in hand (snigger). The more dangerous the better. The chance of being arrested, pummeled by an angry father or having your hand severed by an arab's sabre means that you are a pro "Danger wanker."

Same as "you piece of shit you!"

A thing where one oerson is too freaking scared to say "you piece of shit" so they say "you piece of crap"... they're basically the same thing.

Your mom's idiot boyfriend, who is a piece of crap, and will never grow-up.

It's self explanatory.

Craps; a word to use in plural terms of many peices of crap.

Piece of craps; a word in which a pile of crap is made up of many other craps. (can be used hypothetically as well as literal)
