used as a verb: To disassociate oneself with a person to the point that they are as if dead. This is usually done to a person whose actions are considered malicious.
"She's crazy! You already told her you didnt want to speak to her. You gotta dead her! Don't answer her phone calls and ignore any type of communication she may want to have with you."
