1 definition by Mark Harrison
A young man who has many characteristics of a naughty boy: he's independent and willful; he does what he wants when he wants; he doesn't follow trends, they follow him; he often looks scruffy, but hip; he's not looking for trouble, but there's a sense of danger about him. For these reasons and more, he's irresistible to women. He's a heartbreaker with five o'clock shadow.
Humphrey Bogart was the orginal badboy.
