Snark (noun): a combination of "snide" and "remark". Sarcastic comment(s). Also snarky (adj.) and snarkily (adv.)
But just what is snark? We all think we recognise snark when we see it - it's a tone of teasing, snide, undermining abuse, nasty and knowing, that's spreading through the media. Its practitioners think it's funny, but it isn't big and it certainly isn't clever. So where did it all go wrong? What happened to the black comedy, the clever irony and the pinpoint satire we once admired and how did they turn into a charmless and witless way of speaking?
