Noobanon
The planet from which all noobs are descended from. Supposedly, some noob accidently blew a chunk of their planet off, and that chunk flew through space and eventually crashed into earth. The noobs colonized the San Francisco area and have spread around the world by today.
(after getting blown up by a grenade launcher in Modern Warfare 2) "Geez, I wish that asteroid from Noobanon had never hit earth. Those noobs." "Well you can't blame them."
