Why “callithump” is a great word
CALLITHUMP — [Noun] A noisy, boisterous, and often riotous parade or serenade, typically involving discordant music from improvised instruments. The word is a back-formation from the adjective 'callithumpian', itself an alteration of 'Gallithumpian', a late 18th-century term from Dorset and Devon for a society of noisy radical reformers or disturbers of public order. Unlike a 'parade', which implies a formal, celebratory procession, or a 'charivari', a targeted, mocking serenade for social transgressions, a callithump is a general, anarchic assembly whose primary purpose is cacophonous expression. It is the metallic shriek of a tin trumpet, the percussive clang of a lid on a washtub, and the collective body-heat of a crowd moving without route or reason—a fleeting, physical democracy of noise raised against the silent order of the night.
Etymology
Uncertain. Perhaps from calli- + thump, or an alteration and backformation from "Gallithumpian", a Dorset and Devon word from 1790s for a society of radical social reformers, in reference to "noisy disturbers of elections and meetings
