Vituperation

[Sarah]

The act of vituperating; abuse; severe censure; blame.When a man becomes untractable and inaccessible by fierceness andpride, then vituperation comes upon him. Donne.

[PussyCat]

Vituperation is defined as sustained, harshly critical language, but it is rather more than that. When used effectively vituperation makes the person on the receiving end wish that the earth would open up and swallow them whole and the people not on the receiving think Thank fuck that wasnt me!
However, at its very best vituperation makes the person who is subject to it dissolve into an amoeba and crawl away to hide under the carpet, while the people not subject to it marvel at the aptness of the description and dissolve into helpless laughter.
