The bad version of built different. Instead of being on another level on the high scale (good), being built wrong makes you on another level, just backward (bad). Someone can be built wrong in many ways. Examples are and are not limited to unparalleled stupidity, ultimate cluelessness, horrible luck, or just wrong place wrong time. Unfortunately, most people who are built wrong are shamed and ridiculed because of their built wrongness, despite most of the time, it's not their fault (wrong place wrong time).
