Go on Opra and have a group discussion on what formed the need for group acceptance from non-family members.
get matching tattoo's
with 3 or more people, wearing the same colors, and some illegal activity you can move up to Gang status
Build a club-house....but check with your parrents first before you use their tree in the backyard
Hang out at Denny's after Midnight & intimidate the drunks trying to keep down their food
practice looking cool, tough, and sexy all the same time to win over chicks from dorky guys - performing this in a group needs practice, not cool when everyone in the club all leans up against the corner building the same way, and flexing muscles the same way...kill's the mojo - sorta like 2 chicks showing up at a party with the same outfit on.
Get cool nicknames....avoid names lik Lawrence, Mark, Steve, or D1ck
Anyhow, Im not the club type...good luck with it, be safe and all that stuff.
