Etymology
Origin of vicious
First recorded in 1300–50; Middle English or directly from Anglo-French, from Latin vitiōsus, equivalent to viti(um) “fault, defect, vice” ( see vice 1) + -ōsus -ous
Explanation
Vicious is an adjective that means intentionally harmful or nasty. If you spread vicious rumors about a person, you're telling people things that will hurt her feelings or ruin her reputation. Cut it out! If you're described as vicious, you're someone who does brutal things on purpose, out of ill-will towards others, like beating up defenseless puppies or poisoning the drinking water for a town. You're worse than just mean if you are vicious — in fact, you're evil! People (and puppies) will be wise to keep their distance. Other things, like gossip, animals, or cars from horror movies can be vicious, too.
