Someone who doesn't like being alone enough to be in disagreement with lots of people, so they tend to be in agreement with enough people to try and outnumber anybody who disagrees, but still try and look like someone
nobody will mess with (a poser), that
way the one or the few that really do disagree remain the assholes who actually have consequences coming their
way.
The guy/girl that created the term schrodinger's
asshole didn't know that he/she was his/her own definition of one. He/she liked to argue a lot, but didn't actually like for everybody to be in argument or opposition to him/her, since that would actually mean ending up alone, while everyone else was together on something. He/she hated being alone too much to ever really be an
asshole on his/her own, so he/she created the term schrodinger's
asshole to try and get more people in a group of other schrodinger's assholes just like him/her, that way he/she was guaranteed not to be alone.
