From the Greek sarkasmos and the dialectic snark (a variation of narc, meaning "to irritate people into selling illegal substances") comes the word snarcasm. A form of satirical wit, snarcasm is speech that is directed against an individual with the intent to annoy or cut said individual. In some extreme cases, prides have been fatally wounded as a result of intense application of snarcasm.

Variations of snarcasm would include snarcasmic (he's being very snarcasmic), snarcastic (that's snarcastic!), snarcasmed (she was snarcasmed in that catfight) and snarcasmish (don't you think that's a little snarcasmish?).
