Sorry man, I can't help but lean toward the notion that... well, here's what I saw:
1. Create an excuse to pull down your pants and still seem cool.
2. Shove something long & hard up your ass while they watch.
3. Encourage other young boys to aid you in this act.
4. Introduce an element of danger as to gain respect.
5. Seem brave so that one holds your legs and feet (startin' to sink in yet?)
6. Get sexually excited somehow about fireworks up your butt.
7. Let your "friends" light it...
8. PAIN, PAIN & more PAIN!
9. Your buddies hug you naked while you still proclaim you're straight.
Brilliant.
