noun. Impotent dude (though I guess you could figure out the "dude" part).
Real citation: "Fourth, go back to your psychopharmacologist, have him adjust your dosages and while you’re there, make him give you an ’script for Viagra, Cialis or some other erectile dysfunction drug. With all the pharmaceutical phallus-firmers cluttering the shelves these days, there’s absolutely no reason for anybody to be a limp chimp."
(Judy McGuire, New York Press, http://www.nypress.com/17/7/news&columns/date.cfm)
Made-up citation: "There's a big difference between a limp chimp and a wimp pimp with a gimp. Or is there?"
