A very and an increasingly popular sauce or sandwich spread especially among the Millennial generation and today’s youth, chiefly due to the fact that regular mustard is now almost exclusively eaten mainly by adults in their forties or older, see: Yellow Mustard
My father and mother primarily eat yellow or spicy brown mustard; most or practically all millennials and today’s youth will only eat honey mustard sauce if they even eat any kind of mustard at all
