Benny havens are fingers that are covered with the seasoning and flavouring of Doritos brand tortilla chips.
They are also known as "Dorito fingers".
Benny havens occur after eating Doritos, usually Cooler Ranch flavoured Doritos but also with the other flavours.
They are very common if there are a lot of haven Doritos in the bag.
In writing, benny havens also are referred to as BHs.
