Attempts to resolve the Quandary:

Mrs. deCourcey's sitting room had undergone a ghastly transmogrification from genteel retreat to a pretty fair approximation of a Red Indian potlatch, with scores of painted men and women leaping about in various states of undress, food and drink everywhere (her beautiful chaise soaked with beer!), and the normally lightly lavender-scented air augmented unpleasantly by the eructations of celebrants who were now well into their second day of merrymaking.

The potlatch used to be a feast to augment social status when the benefactor was transmogrified in the eyes of the Kawkluti tribe by giving away almost all of their material possessions; but in these ‘modern’ times it’s more likely to be a big party celebrating a baby shower or graduation replete with beer-driven eructations.

The potlatch being a festivity foreign to Scotland, Miss MacCaul hit on the idea of comparing it with a ceilidh, one dark winter morning transmogrifying with 'Chinookan' face paint herself and her class of wee bairns before parading single file round the room singing Auld Lang Syne - to a quasi 'canon in augmentation' from the caretaker, whose inebriate eructations hocketed his maudlin but enthusiastic contribution.

Unable to find work as an office temp, Jared transmogrified his resume into that of a professional celebrant, stating his readiness to participate in any festivity whatsoever, citing eructation as a professional skill, and augmenting his fairly homogeneous work experience (frat parties) with a claim that in the summer of 2009 he had officiated at a Kwakwaka'wakw potlatch.
