Text Attack
Sending one text message as many times as possible in a short period of time to one person causing their phone to freeze up or reboot. Is most effective when five or more people text one persons phone sending them upwards of 100 messages each. Easier to do pre smartphone era but is still possible with the resend feature on most phones being easily accessible.
"I text attacked Jess yesterday to the point where she called me crying saying her phone was broken."
