Jargon refers more accurately to a set of words or specialized language used exclusively by a particular group of people. SNAFU, Elevator pitch, *.elfie could be used by anybody, they're not considered jargon.
"monkey-patch" and "spike" might be considered developer jargon.
Jargon should only be plural if you are specifically referring to more than one specialized language or jargon.
