Any predictably morose and/or ignorant opinion expressed by a victim of the emo trend. Most emopinions center on the subjects of false sense of persecution, "Why does everyone hate us?" attention-getting self debasement, "My life is so terrible!" and the mistaken belief that the emo trend is something unique and counterculture, "We are true rebels!" despite the fact that the emo look is entirely conformist and the whiny/tantrum rock they listen to is completely unoriginal and contrived.
I asked that kid with the emotenuse why he was part of such a stupid trend and all he did was spout bitchy, predictable emopinions.
The practice of typing out internet facial expressions as a form of emoting, such as "*eyeroll*", or "*evil grin*"; most commonly used in chat correspondence, prior to the existence of emoticons, smileys, and emoji.
Ian detests seeing emoping on Facebook, and is going to bite off everyone's nose if he has to read one more *eyeroll* in his newsfeed.
