Knowing it's just shortened "pro-abortion" is obvious enough, at least. Quick search shows this to be a long-used term in right wing circles, just can't say I remember seeing this shortened version of it until recently. Not that it would change my response or anything, it's an equally balderdash, made up term without evidence to support its existence. Like "groomers", despite recent news reports related to fairly large-scale law enforcement operations or legal proceedings against individuals and organizations relating to child sexual abuse.
