My late wife detested the yellow mustard. When I used it .. and I love it because of the sharp vinegar flavor .. she called it "baby-sh*t" mustard.
LOL. My mom said that too. I guess it stuck withe because every time I see yellow mustard, I think, baby poo.
I always try to put Frenches yellow mustard on baloney on white bread sandwiches, but Gulden's golden on ham, baloney, or corned beef, on hero or club bread. Not sure why. Just seems to go better that way.
