The Original DDOS Attack!

If your boyfriend's pissing you off because he's been ignoring all your calls and texts, then compose a new text message on your cell and add him as the recipient, but do it for all 10 recipient-slots for that same message. It only takes a second to do it, so compose a new text and do it again, but repeat the process like 10 more times in a row.

And, there you have it. Spiteful revenge from afar. In the matter of 30 seconds, you've effectively disabled that jackass's phone as 100+ consecutive text messages try to reach his cell at once, like a series of onslaughts. Depending how angry and dysfunctional you are, you can keep this going for a painfully long time.
