Legal Definition of 'Hot Dog'

I was just looking up a definition of "hot tub" for a class project. I didn't find it, but where it would have been I instead came across a Kansas decision that attempts to define what a "hot dog" is.

The words 'hot dogs' are here used to describe some form of meat often found in the center of sandwiches which are designed to be eatable, even if of doubtful digestibility.

Another case refers to them as a "small sausage of unknown content". In case you were wondering.
