crackstacio
A "crackstacio" refers to a pistachio in-shell and the game-like enjoyment we get from prying them open -- to the easiest levels(one random out-of-shell) to midlevel (fairly easy to pop open) to the game boss (the almost or completely closed) and the crack-like reward of delicious pistachios for our efforts. Other products can be pistachio-flavored or have (shelled) pistachios in them because getting them out of the shell is almost a mini game with yourself.
I'm reading Mystic River again with wine and crackstacios.
