The condition of feeling sick, or about to be sick, when texting, usually rapidly, because your recapping last nights events while hungover. This condition is usually accompanied by nervousness and anxiety because the booze induced hangover has helped you see such said events much clearer than anyone else. Thus, you're feverishly texting to all your friends to help them see the light. The flood of memories, usually in chaotic, random order and the translation of those memories into usually incoherent, and often times, wrong, string of text messages causes the texter to become sick to his or her stomach.
