An E-vorce is when your significant other changes their "marital status" on myspace, facebook, etc. When they are upset with you. This can be temporary or permanent depending on the seriousness of the situataion.
"Hey Blue Eyes, your facebook says you are single again, wanna make out?
"No, my wife just e-vorced me for the day since I forgot to put the seat down, she will get over it and fix my status later"
