The act of sending unsolicited texts that are not answering a question, making a request, have an obvious response, any response would seem pointless, or are otherwise considered pointless by the recipient. These are texts that serve no two-way-communication-purpose and seem to be just informing you of something that requires no further action or response.
Texter 1: I'm eating breakfast.
Texter 2: man, quit text blogging me
Texter 1: I just wanted to say I'm eating breakfast.
Texter 2: Good for you.
