Text-fishing

the sport of sending out casual text messages to a series of people you would like to hook-up with in rapid succession. The idea is to stimulate a meaningful response, known as a bite, from one or more of them in hopes of catalyzing intimate relations.

Texting multiple people, like casting multiple fishing lines, waiting to see who responds. Usually done when in moderate to extreme levels of boredom, or to procrastinate in some way.
