In the NYC gay scene (no doubt elsewhere, as well) of the 1960-70s a "blue oyster" was the head of a very aroused penis, especially one that had been teased in various ways without orgasm for a long time. The glans takes on a cyanotic blue cast, probably do to the prolonged erection.
My girlfriend sure loves to eat blue oysters in cream-sauce.

A Blue Oyster is a cocktail. Take a shot (or two, depending on tolerance) of WAVE Blue Raspberry vodka and mix it with a can of Mountain Dew White Out. It goes best while listening to Blue Oyster Cult. It has a baby blue color and is very sweet.
We spent New Year's eve drinking Blue Oysters while listening to Don't Fear the Reaper and Cities on Flame with Rock and Roll.
