As a New Orleanian, I spend a lot of time thinking and talking about food. Every conversation here will eventually turn to food, glorious food. Growing up in a Greek family was similar, which is one reason I assimilated here so rapidly. That's why I think this Victorian term for OTT extravagance should be revived:
Butter upon bacon
Usage: I think that putting glitter on that beaded shirt is a bit too butter upon bacon.
This one is a potential winner, I can see it sweeping the foodie scene. Hopefully, the dread Guy Fieri won't pick it up but you gotta take the bitter with the sweet sometimes.
