Those explanations are listed along with the reasons why they are not true

I found a fascinating one on the alleged (and also false) origins of the word "shit." The story is that "shit" actually stood/stands for "ship high in transit," and referred to the shipping of dung. Like the "fuck" acronym myth, it's not true, but it's amusing as hell. Makes you wish it was true, it's so clever.
