Could frammish be a portmanteau then? Condensing "frammis-ish" to frammish - as in gizmo-like, maybe the thing you need to build which may or may not be a distinct component?
frammis, frammistat, frob, frobnicate, and a few others are "hacker" words that I learned from downloading text files on bulletin boards in the 80s. i only ever heard them from that source, until i had a manager from that era except he was all military software background. (yeesh, he was awful)
