"So if recessionista and fembot are not really puns, what are they? They’re neolexic portmanteaus, in which root words are brutally slammed together with cavalier lack of wit. “Neolexic portmanteau” is a mouthful, so instead we shall choose a simpler handle. Sherry-manteau, catastrounity, misceg-formation, piss-poortmanteau, and poor-man’s-toes all proffer themselves as alternatives, but they are still laborsome. Therefore, I christen these neolexic portmanteaus adjoinages—a functioning portmanteau pun, in case you failed to see, on adjoin and coinage."
