A "party bro" is the highest regarded status of all bro-hood. Sought by many and achieved by few, party bros are an endangered breed of superhuman, notoriously sustaining themselves for months at a time on nothing more than alcohol, tobacco, drugs, sex and Reeespect!

If you're hot and happen to see a party bro, fuck them immediately, as this is the only conservation effort that has had success in sustaining their dwindling numbers.
He's such a party bro!
I wish I was a party bro!
I just fucked a party bro!
