If only it was as easy as this.
4. Beat Down
The most common form of gang initiation is one you would expect from these type of people. In order to prove yourself as worthy to be in said gang, you must endure getting beat up by either a specific large individual, or the entire gang itself. I'm not talking about a little "middle-school" round of bloody knuckles either, you could (will) be thrown against the ground, jumped on repeatedly, smashed in the face a hundred times, kicked in the privates another hundred times, and punched in the gut all while people hold you down and restrain you. (Some gangs may even use weapons such as baseball bats)
Some more recent gangs have resorted to even more barbaric initiations.
If you're lucky, you could expect a couple bruises on your face and back along with a few scrapes and cuts on your legs. In other cases, you could be beaten to the point of permanent psychological and/or physical damage. Worst yet, some people have been known to die from such initiations.
Alterations have been made of this initiations such as receiving a single semi-fatal blow into the sternum, being forced to fight and beat your future gang "amigos", fighting your way out of a circling group of pain and even picking up randomly dispersed pennies off the ground as you push through a crowd of gang members trying to beat your eyes out of their sockets.
