Doing something big that
will get you in trouble, but you
don't care. This term derives from how
John Hancock wrote his name the biggest on The Declaration of Independence.
John: I just banged eight fat chicks!
Bob: Your wife is going to be pissed!
John: I don't care! I love Hancocking!
Tim robbed a bank, walked across the street and started jerking off in front of everyone. The police were on their way. He didn't worry a bit. He's really great at Hancocking.
