The text version of "drunk dialing", in which you text someone while under the influence of drugs or alcohol. The resulting texts are often composed without a filter between the fingers and the brain. As such, unprotected sex often leads to situations that are, at best, uncomfortable.
Dude 1: Dude, how did Emily end up dating such a troll?

Dude 2: She met him on myspace, man, and they started having unprotected text. Next thing you know, she can't get rid of him...

Dude 1: Woah...we should totally get high...
