A topic, phrase or word that emotionally sets someone off. Could refer to anger, or reliving a traumatic experience. Sometimes this is logical, other times it seems like an attention grab. It is fairly common for certain communities on, for example, Livejournal to be overly sensitive to
people's 'triggers' (often but not
always relating to sexual assault)--any mention of violence
may be censored.
(1) Man, I know I shouldn't have gone off on
Eric that way, but that racist
joke he made triggered me big time and I flipped my shit.
(2) I got kicked off that livejournal group for not lj-cutting my post talking about the rape
scene in the movie I watched last night. Some girl said it triggered her and the mods were on her side.
