When a girl or guy, usually one you don't want to be associated with, smothers you with text messages to the point of calling the cops on them.
My crazy ex girlfriend who still wants something from me likes to initiate in textual harassment.
When someone is texting you and it's far too sexual for your liking. Unwanted texutal harassment.
Sarah was messaging me last night, it was textual harassment.
The act when one person sends another person a series of small, meaningless (by themselves and not as a whole), pointless, annoying, gear grinding redundant messages with the purpose of conveying a message.

Pesron1: Today?
