Lafarga
A Lafarga is a person who thinks they're the best. They only like girls who are hot and don't have any brains. When they play sports, they win every time and act like it was nothing.
'I'm not even trying. I'm a Lafarga.'
'He said he's a Lafarga. I asked him what that meant. He just texted me a selfie.'
'She's a Lafarga. She cheated on her math test and still called it a win.'
