One of the best ways to trick people into thinking you know what you're talking about is by employing a clever conversational trick known as sesquipedalian macropolysyllabification.

What exactly is sesquipedalian macropolysyllabification? Well, to put it in simple terms, sesquipedalian macropolysyllabification is quaquaversal lucubration about pervicacious torosity and diverticular prosiliency in diatonic formication and chromatic papulation, engendering carotic carmination and decubital nyctalopia, causing borborygmic susurration, teratological urticulation, macroptic dysmimia, bregmatic obstipation, crassamental quisquiliousness, hircinous olophonia and unflexanimous luxation, often producing volmerine cacumination and mitotic ramuliferousness leading to operculate onagerosity and testaceous favillousness, as well as faucal obsonation, parallelepipedal psellismus, pigritudinous mysophia, cimicidal conspurcation, mollitious deglutition and cephalotripsical stultitiousness, resulting despite Hesychastic omphaloskepsis, in epenetic opistography, boustrophedonic malacology, lampadodromic evagination, chartulary cadastration, merognostic heautotimerousness, favaginous moliminosity, fatiscent operosity, temulencious libration and otological oscininity, aggravated by tardigrade inturgescence, nucamentacious oliguria, emunctory sternutation, veneficial pediculation, fremescent dyskinesia, hispidinous cynanthropy, torminal opitulation, crapulous vellication, hippuric rhinodynia, dyspneic nimiety and favillous erethism, and culminating in opisthographic inconcinnity, scotophiliac lipothimia, banaustic rhinorrhea, dehiscent fasciculation, oncological vomiturition, nevoid paludality, exomphalic invultuation, mysophiliac excrementatiousness, flagitious dysphoria, lipogrammatic bradygraphy, orectic aprosexia, parataxic parorexia, lucubicidal nutation, permutational paranomasia, rhoncial fremitus, specular subsaltation, crapulous crepitation, ithyphallic acervation, procephalic dyscrasia, volitional volitation, piscine dermatology, proleptic pistology, verrucous alopecia, hendecaphonic combinatoriality, microaerophilic pandiculation and quasihemidemisemibreviate illation.

And now that you know what it is, the next time a regnant entity catechizes the validity of the avouchment that your recent incumbency primarily consists of otiose capering, you can, with effusing aplomb, discombobulate them using unveracious prevarications whose troublous interpretation will circuitously oppugn their avowal (with precipitance) and disencumber you from any ulterior assiduity.

Yes, it's just that abecedarian!
