(n.) A violation of netiquette, like flaming or a site-specific attack (denial of service, sock puppets, spamming, et al.). It is commonly deployed by individuals attempting to redress a perceived slight, interpersonal confrontation, or who are merely thin-skinned miscreants. Comments and actions may range from snide or desultory remarks on social networking websites, to full-blown character assassination conducted on services such as DontDateHimGirl.com, Facebook, MySpace, and others. The frst consonant often capitalized.
