Comparable to thingy or doo-hickey, eunocle encompasses anything and everything and serves as delicious substitute for any idea or word. Depending on the context it is either positive or derogatory.
"Of course I'll take some more raisins! pop some of those eunocles right in there" he said, gesturing frantically to his mouth.
Like thingy, thingamajig, but also dude, and expressions like gee willikers, or heaven sakes eunocle encompasses nearly anything--a person, place or thing, or state of mind.
"Hillary, pick your eunocles up off the stairs!"
"He's one tough eunocle."
"Jesus HPR eunocles!"
