Textjacking is when you receive a text message from a wrong number and you send a random response to highjack the conversation.
Wrong number: "its lexy. where r u?"
Textjacking: "the border patrol is searching the car!! i think they r gonna find it!"
Wrong number: "find wut? who is this?"
Textjacking: "3lb just like they wanted. think im good, they dont even have a dog lol."
