the english term bottle just appeared to be a bad translation of the german means of "fläche".

So "fläche" means plane, not flasche (bottle), not even "surface", which means "oberfläche", and the corresponding term seems to have made its way into popculture.

Dissecting a Klein bottle into halves along its plane of symmetry results in two mirror image Möbius strips, which is mind blowing for non mathemathicans(can be..)

Now this is real besserwisserism, and i´m praising berlin for its pavement full of dogshit...
