Chris, go out and shit to the extreme!
I've always been of the opinion that, other than not being disciplined, Borb never potty trained Chris. For kids, toilet training starts at around age 3, and Chris was a mute at the time. So, It must've been hard for Chris to communicate to his parents about using the bathroom, and the mentality just stuck. Adding that Chris gets legit scared shitless (or becomes stressed to the point of shitting himself), it's no wonder the last resort was to wear Butt Garments, and Chris being Chris, ironically didn't want to wear them cause they were for babies, and didn't see any problem for his rape victim mother to wash his then 20 year old soiled pants. Ironically, should Chris live to be around 80, he will have to wear diapers.
