To break up with your significant other via email rather than have the courage to do it face to face.
by Sophie Chambers October 21, 2010
To ditch someone via e-mail, im or text message. Usually practiced because the e-dumper does not have the balls to tell the e-dumpee to his/her face that he/she is dumped.
"I was chatting with this chick I met on the internet for a couple weeks, then she e-dumped me for someone she met in real life."
