I've heard the term used at least as far back as the 90s. The phrase "cut the toxic people out of your life" comes up a lot. I suspect it originated with either 12-step programs or psychologists. Seems like good advice, except for the part where it's basically running from interpersonal conflict instead of dealing with it. In some situations with really unbalanced people it's the best option, though.
