The action of the large lips of black people who eat greasy food (such as fried chicken).

One is crackle-smackin when wearing a new set of veneers that are much appreciated by homeboys, haters, and ratchets of the community... The veneers must be made of porcelain (known by some as crackleware) and emit a florescent glow when compared to it's immediate surroundings.

The -smackin suffix refers to the proximity of the veneers to the lips and mouth
