word sniper
pronounciation: wərd snÄ«pərnoun1. A verbal marksman who attacks someone else in a comment section by taking a potshot at them but doesn’t really say anything of substance or worth. Word snipers are not interested in having a real conversation. They normally just make a single, negative reply to another person’s comment and take off, never to be heard from again. Their potshot may be related or unrelated to the subject of discussion. Unlike trolls, word snipers don’t continually harass other people. They get in, take their shot, and they’re gone. Trolls tend to hound people mercilessly for as long as they can get away with it.
Wow, that word sniper was viscous and hurtful while managing to say nothing of consequence.
