vituperation

Vituperation is a noun that refers to critical, abusive language. It's always a messy scene when a political debate slips into vituperation.

Vituperation is from the Latin root words vitium, meaning "a fault or defect," and parare, meaning provide, which combined to make vituperare meaning "disparage." Vituperation can also be used to refer to feelings of bitter resentment and deep-seated antipathy toward another — like your vituperation toward the meter maid who just placed that ticket on your windshield.
