Nickname for a big time chicken eater.
Especially apropos to any individual who eats Popeye's or KFC more than four meals per week or buys a whole barrel (tub) for themself and hides leftovers for snack treats.
Carrying around a plastic bag of "chicken for later" or eating it while driving certainly merits this monicker.
"Whuz acrackalackin, Fingerlickin' Chicken?"
"Why'ont you save me a juicy breast, OK?
"Huh?"
Finger Dicking is when you are doing a job but are getting nowhere due to incompetence and someone else come over and completes it immediately.
We had E&E personnel finger dicking a duct for a shaft driven compressor on a CV-22 for an hour and a half. The expeditor came and completed the job in fifteen seconds.
