labroin
A Labroin is a guy who acts like he's got it all figured out, but he's just as lost as the rest of us. Still, he'll be there for you even if he calls you names and cusses you out.
Labroin says, 'I know everything,' then asks you for help on a math problem.
Labroin texts you: 'I'll help you, but don't expect me to be nice about it.'
Labroin gives you advice, then says, 'I'm the only one who knows what I'm talking about.'
