Top Definition
A profound expression on one's face that resembles that of a shit eat'n grin. Usually remains permanent at all times regardless of the situation. Dates back to an ancient Albanian custom to intimidate their enemies and daughter-in-laws. Has recently become a trend throughout the civilized world and has replaced breast augmentations as the number one plastic surgery procedure.
