verb
Informal. to promote something or express opinions vociferously.
Tub-thump, a very rare word, is a back formation of tub-thumper “a vociferous supporter of a cause.” The verb tub-thump was coined by the British author Herman C. McNeile (1888–1937), whose pen name was “Sapper,” and who wrote the series of thrillers whose hero was Bulldog Drummond. The only other author to use the verb tub-thump was the American poet and editor Ezra Pound (1885-1972). Tub-thump entered English in 1920.
Ever eager to tub-thump America’s vast superiority, local civic chauvinists wanted our homegrown exposition to outstrip them all.

adjective
changeable; volatile; fickle; flighty; erratic: a mercurial nature.
The English adjective mercurial ultimately comes from the Latin adjective mercuriālis “of or pertaining to Mercurius“ (i.e., the god Mercury), whose original function was as god of commerce, transporters of goods (especially of grain), and shopkeepers. Latin also has the plural noun, derived from the adjective, Mercuriālēs, the name of a guild of merchants. Mercurius is related to merx (stem merc-) “goods, wares, commodities” (and the ultimate source of English merchant and merchandise). By classical times Mercury was completely identified with the Greek god Hermes—the messenger of the gods because he was fast-moving, and always on the move, negotiating, fast-talking, making deals, flimflamming, playing tricks. Mercurius also acquired the meaning “pertaining to the planet Mercury” (Stella Mercuriī, “Star of Mercury,” a translation of Greek astḕr toû Hermoû), the fastest moving of the planets. Mercurial entered English in the 14th century in the sense “pertaining to the planet Mercury.”

noun
the deceptive tactic of simulating grassroots support for a product, cause, etc., undertaken by people or organizations with an interest in shaping public opinion: In some countries astroturfing is banned, and this includes sponsored blog posts.
Astroturfing was originally an Americanism, coined in 1974, meaning “to cover an area with Astroturf (a carpetlike covering made of vinyl and nylon to resemble turf, used for athletic fields, patios, etc.).” Twenty years later (1993) the current sense of Astroturfing “the deceptive tactic of simulating grassroots support for a product or cause, undertaken to influence public opinion” first appeared in Canadian and Australian newspapers.
An aide said Mr. Markey hoped to combat the tactic of astroturfing in which a professional lobbying effort is made to seem like a grass-roots movement.
