Mouth widening cope

[BrutusTheBulldozer]

I know a lot of people who recommend "diy mouth widening" by stretching your lips laterally with either your hands or 3d printed/Chinese devices n shit but wouldn't this technically be cope since it is just temporary?

Your lips just stretch temporarily and return back to their original position afterwards, no?

Can someone enlighten me
