The earliest form should be "derailment". "Cheating" is not reading "cup", but reading "cup", which means sneaking around, sneaking around. "Black" means darkness, and "cheating" means fault, so "cheating" means knowing and should not be borne by someone (but he is forced to bear it).

Later, it was mistakenly written as a scapegoat.

Because it looks too much like a verb-object phrase, "back" is regarded as a verb and pronounced as "cup"

And "strange" has become synonymous with the image of "responsible for others".

Then "taking the blame" is simply called "taking the blame".
