Some of the older generation folk in Hong Kong voiced their disappointment at their misbehaving kids that caused them so much grief. They would say something like "生舊叉燒好過生你", which would translate to, "better to have given birth to a piece of cha siu/bbq pork than you!". BBQ pork is one of those representative delicious things that everyone craved so much in the old times (bbq pork over rice was one of the definitive comfort foods) and some of the older folk may remember the days when bbq pork was peddeled off a push cart, the grilled meats dangling so much to the point that the bigger pieces would literally scrape the ground.
Also I read somewhere that there's an old saying in Japanese, basically about the winter season of buri (or kanburi) which is a yellowtail variant. Something about "even if you have to sell your wife, you must have a taste of winter buri". Or maybe it was about some other fish.
What other funny wordly expressions are there that involve food?
