A rather brutal and secretive group of prison gangs in South Africa. Number gangs have numbers instead of names, and typically have millitary-style hierarchy, extensive tattoos, strict internal laws, and require violence against prison staff for initiation. The 28 Gang also has a system for distributing sex between new recruits and established members. Recently featured on a BBC documentary.
Numbers gangs include the 26s, 27s, 28s, etc...

Physical damage. To "do a number" in an aggressive situation frequently implies hurting someone, usually a particular body part. For example a number is used in the phrases "I'm going to pop you one" and "a quick one-two" (in boxing).
Rough him up a little, then do a number on his face.
