thinking again about a TF in the style of "whatever is said about you becomes true"

there is the first form of it being done on purpose. "How are you going to take that collar off with your big, useless paws?"

but there's ALSO the other fun kind of it not being intentional - other's perceptions of the person are altered, and when pointed out, the person changes to fit it

(ebikiyo's The Fox Tapes is a great example of the latter)

honestly I'm just a sucker for reality change TF where it's caused by someone stating something as true, or the like. or writing it down. Like scribbling over someone's occupation on a resume with CATGIRL.
