He had to be blatant and rather banal as he explained to her that it was not a billet-doux when he wrote that her ectopic use of sciential vocabulary was miles away from resembling any sort of witty badinage.

Pancho was in love and he filled the air with cheery badinage when he was among his friends and sent off flowery billet-doux to his new lady love, and although his current Franken-girlfriend was much more aware and sciential than his previous (inflatable, air-headed) one, she apparently had at least one ectopic part, for when he pinched her cheek (the one below, not the one above), he could feel her heartbeat.

By using erudite language and a haughty demeanor that were completely devoid of lightness, humor and badinage, I somehow convinced Mildred that I was very serious, or even dour, and supremely sciential in all the weighty subjects of our time, and it was ectopic to her that I then sent her a risque billet-doux, a box of donuts, and a ticket to join me and watch a mud-wrestling contest at a biker hangout on the outskirts of town.

'What would billet-doux?' is an example of how badinage is reliant upon the ectopic potential of language in the way that this sentence is an example of how particularly shonky badinage might rely on sciential style.

I had every intention of writing my sweetheart a heartfelt billet-doux, but one drink led to another and my pen lost its way, so that after seventeen pages of rambling badinage and an overly-sciential tone (I actually used the word ectopic in a love-letter, if you can believe that), the missive ended up offending rather than seducing my beloved Hermione; and as a consequence I was obliged for an entire fortnight to take up lodging with our three pugs (Gandalf the Grey, Oprah, and Joey Buttafuoco), our five hedgehogs (Larry, Curly, Moe, Shemp, and Arsenio Hall), our six Shetland ponies (Brutal Bill, Old Fatty Lumpkin, Biscuits 'n' Gravy, Shadowfax, Lord o' th' Dance, and Mel Tormay), our baby rhinoceros (Cyrano de Bergerac), our seven tapirs (C-3PO, Audrey Hepburn, Combat Carl, Cheech, The Artist Formerly Known as Prince, Lieutenant Uhura, and Kevin Kline), and our "fleet" of three carrier-pigeons (Punctual Pete, Tardy Marty, and Laid-Back Lenny); as for our ridiculously overweight giraffe Frodo, he had just been set free by the nefarious Fusco Brothers, and the zany spree of madcap adventures detailed in my best-smeller Fat Giraffe About Town had already been set in motion.
