Strictly speaking, a pledge brother is any person that is going through the same pledgeship as yours within a certain fraternity. And, they are in the same graduating class. They are the ones you bond the most with, and they are usually the ones that got your back for the rest of your life. Shit goes down when someone tries to mess with any of them. Their relationship is similar to that of a blood brother.
Joe: Honestly, if anyone happens to mess with my pledge brothers, they're fucked.
Mike: Yeah, same here. We're brothers in the bond.
Used by the native peoples on the reserve. They refer to everyone as their brothers becasue they belive that everyone is a brother from another mother. Usually used on freindly terms.
"You aint no Brother"
"Fuck you brohter"
"Hey there brother hows it going"
"Were all brothers"
Source of possibly the most used Drum and Bass break ever, this song by The Winstons made for some of the best (particularly old-school) tracks ever. The high tempo of the original and the tight, compressed sound of the solo made for a natural break that moves the booties.
