Top definition
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.

Stupid male teenagers that have a tendency of breaking the law but according to Fiction Stories (maybe Wattpad) Bad boys have a heart and let a beautiful nerd change theyre lives for the good. But then the Beautiful nerd finds out that the Bad Boy fights in an arena every Saturday night and things get messed up from there.

They also attract every girl on the planet... exept for the ones that hate them, and dont believe theyre alive!

Advice- Dont flirt with them because apparently they hate that
