A special type of membership/inclusion/title given to bros who drive their friends around while they're looking for a place to drink on a dry night until they forget they're supposed to be looking for a place to drink, putting up with the crap they pull, the smell of beer in the car while remaining completely sober, and taking them to a drive through or two, wasting about four hours of gas on the way.
Wow Bertini, you showed a lot of bromanship driving us around while we were completely slammed there buddy, thanks.
