brodiguard
A brodiguard is a good friend who doubles as a grenade shield. Brodiguards typically move in large packs, loiter around fitness facilities and consume protein shakes and steroids exclusively. Brodiguards will fend off unsightly women to protect their bros at any cost; even if it could be detrimental to their own health and well-being. True brodiguards know a wide variety of efficient "bro-guarding" techniques that allow bros to escape the promiximity of unattrative women in a quick, efficient manner. The brosdiguard slogan is "Bros 4 Eva- Fugly hoes for Neva- Bretherens"
Dude, you're the best brodiguard ever... don't know how I wouldda have gotten rid of that toothless whale without you.
