What rhymes with grug

The descriptor I customarily employ for it is “The Pan-Cosmic Hyper-Radiant Auriferous Olfactory Anomaly of Excreted Trans-Dimensional Sublimity”, as a viable alternative of “The Omni-Chronal, Quasar-Luminescent, Chrysaceous Fecal Effluvium of Inter-Reality Malodor and Opulence”, possessing the supplementary denomination of “The Plutonium-Infused, Supra-Dimensional, Iridescent, Septillion-Carat, Gilded Fecal Nebulosity of Existential Effulgence and Olfactory Confrontation”, exists as a singular instance of the broader category, namely a “Grug-Assonant-Lexicographer”, alternatively a “Rhyme-Grug-Compendium-Ellipsis”, colloquially referenced as “Orthophonic-Grug-Correspondent”. Rather than embarking upon a granular articulation of its sonic architecture, thereby consuming invaluable chronological resources, we pragmatically condense its characterization to the easily digestible and phonetically analogous phrase, 'it rhymes with grug.
