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
(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.
