In rugby - a Bismarck yellow is when a yellow card is given for a fantastic bone-crunching tackle which is (incorrectly) deemed to be a shoulder charge.

Some would suggest that a certain incident could be deemed a yellow card based on the Bismarck criteria.

Others would suggest that the referee was bought.
Come on Mr Ref, that's a Bismarck yellow

That wasn't a yellow, but I suppose that could be a Bismarck yellow
