Dead Birds 

A Hardcore gang in the Central Valley of California. Includes various freaks and misfits. Each member has a name, and of course, each name is a bird. The founders call themselves; Hawx and Shags.
The gang has no specific purpose, with no prominent enemy.

Me: "Dude, why the ---- do you have 'Crow' tattoo'd on your wrist."
David crow "Porque I'm a part of Dead Birds now, ese."
Me: "Dear god, they got you too?"
