John Hancock 

(n.) American shipping magnate and possible smuggler who became famous for his role in the American Revolution. He served as President of the Second Continental Congress, was famously a signatory to the Declaration of Independence, and later became the first post colonial governor of Massachusetts. In addition to these accomplishments, Hancock was a prolific author on the subject of masturbation. He wrote several authoritative treatises on the matter (several of which were banned on the orders of George Washington), and famously challenged the widely-held opinion of his fellow Founding Father, Dr. Benjamin Rush, that masturbation caused blindness and hairy palms.

John Hancock was one of America's most illustrious founding fathers and early sex educators.

John Hancocked 

To be "John Handcocked" is to have a man ejaculate into his hand - and with the semen still pooled in his hand - slap an individual across the face. The name derives from the man's proverbial "ink" which spouts from his "pen." He then claims what is rightfully his by marking his territory.

This is most appropriate at Ugly Sweater Christmas Parties, or when a prostitute gets out of line. Especially applicable to any girls that may own a California Tan boutique and hail from Appalachia.

Kristen: "Oh my god, you'll never believe what Paul did last night!"

Sarah: "What?"

Kristen: "He nutted in his hand and slapped me across the face with it!"

Sarah: "Oh fuck, Nathan has John Hancocked me all the time, it's not a big deal, he's just claiming what is his."

YOU: Aren't you afraid of AIDS?

YOUR BUDDY: No, I'm a John Handcock.

One shizza guy. He signed the Decleration of Independence first. He totally owned the other founding fathers.

If I live in the 1700's I would so go clubbing with John Hancock.
