When you play basketball for a long period of time and you dont shave your face and it gets dirty and finally when you start "sucking" like oh i dont know say Pullen off the K-state team. Finally it gets to the point of no return; you get crabs in your beard.
You know, when shit needs done, you "hit the beard". Just like Antonio Montana (Scarface) when he shivvs one of Fidel Castros top henchmen..
Manny-The boss needs us to take the hit out on that gut over there, that is our required target to freedom.
Antonio- ¿Que te pasa? Let's "hit the beard" and go to America! ¡Vamanos!
