Finger lickin good is a term used for a woman who is a french fry and is always a new salty taste. It also refers to a food that has multiple names such as: VAGINA, PUSSY, ASS, and also THICC BOOTAY. Finger lickin good can also be represented as a term for somebody who is a fat pig and cant stop eating.
Example: "OOOOOH, Kims ass looks so Finger lickin good right now i might just want a bite!"
kfc adverts would have you believe that their food is "finger-lickin' good", but many people disagree, and find this particular brand of fried bird entrails to be somewhat unpleasant - hence tarnishing the positivity of the phrase.
thus, "ball-lickin' good" has become the phrase of choice to signify something that really is quite exceptionally good. logically speaking, this makes more sense: surveys have shown that 97% of men would rather have their balls licked than their fingers.
Example: "fried fake fast-food chicken may be finger-lickin' good, but a proper roast is ball-lickin' good"
Example: Jo: My golly these are some dick lickin' good mashed pertaters!
Mo: *covers dick in mashed potatoes* Lick them off.
Jo: Coitanly, because those pertaters are dick lickin' good!
