an acronym: Jar Of Pickles - coming from the latin jarus o pickli, A container, usually made of glass, filled to the brim with vinegar, and stuffed with some type of organic substance, frequently pickles. Pickled cucumbers, pickled tomatoes, pickled plums, pickled infant heads, pickled mangoes! you can technically pickle almost anything!
....and I mean anything.
Bill: Don't open that container (possibly made of glass), containing vinegar, and organic matter: it's a j.o.p.
Harrold: I know i'm hungry!
Buffallo Bill: you eat infants heads?
Hannibal Lecter: ...maybe...Professor Snape
: Cannibalism will not be tolerated. Detention.
