The name for a "Jewish Mexican", Jewish as in the terminology when one "Acts like a Jew", a.k.a., a total and complete Douchebag. Of course, they need to be a beaner as well, hence the "Mex", but that's secondary, which is why it's second in chronological order.
"That god damned beaner just hopped over my fence. Fucking Jumex."
