Fat Bitch Killer, the name of a "gang" of poor white boys from the central coast of Oregon. Also used as a derogatory term for an unattractive large woman. Since there is nothing better in Oregon to do, naturally a band of underprivelaged young men got together to pick on the ugly fat bitches, which, let me tell you, there are a lot of in Oregon.
Look at that FBK in the Suburu! That bitch looks like she just ate a small third world country!
