When someone you are in a relationship with breaks up with you through a text. NO phone call or face to face, but a text dump.
Can you believe that jerk? He pulled a text dump. I knew I should have text dumped him when I had the chance.

Going to the bathroom (or other private place) exclusively to send/receive a text message. Usually to hide the fact that your texting someone other than the person/people you are with.
The boy I was on date with was lame, so at dinner I text dumped Sasha to see what she was up to when I ditched the loser.
