Becky Grin

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.

As the blackjack dealer sucked the last remaining chip from my stack, all she did was stare at me with that Becky Grin.
