The familiar fast-food fried-chicken chain KFC (formerly Kentucky Fried Chicken) distributes packets of butter-flavoured margarine with some of its meals. Although no nutritional information is available at KFC's website, it's worth noting that at slightly-warmer-than-room-temperature, the oily substance seems to separate into three distinctly unappetizing layers. This product is branded as "Bettah Buttah".
My ex-boyfriend Pucky once related to me how he and another ex-boyfriend (i.e., not me) once had impromptu sex in the car and the only thing available for lube was a packet of KFC "Bettah Buttah". I found this incredibly absurdist in a white-trash-spectacle kind of way. Taking inspiration from Spike Lee's 1990 film "Mo' Better Blues", I referred to the incident as "mo' bettah lube" and unleashed the anecdote onto the channel sometime ca 1997.
