MacMill
A person who thinks they're the king of the hill, even though they're just a smelly, clueless meatball who can't even tie their own shoes.
@joe_smith Why do you think you're the best? You're just a sad, sweaty potato in a hoodie.
My cousin thinks he's a MacMill because he knows how to do a push-up. Poor kid.
You're not a MacMill, you're just a guy who uses the word 'flavor' wrong.
