A term commonly used with great fury in reference to your sibling allowing the dog to escape for a few minutes. Although it may not seem fit, being labeled a chicken fucker is sufficient verbal punishment for letting the dog escape. It's even more delightful when you get called one by a 10 year old.
(horrific southern drawl)* "Jarrrred, you motherfucken chicken fucker!, you let the fucken dawg out and now I'm gonna tell mom that you and your friends raped me." "You two-bit chicken shit!"
