God! That parent and child bowl was so disgusting! I threw up in the bathroom.
A very common food item, though the name for it is a little weird. 親子丼 is Parent and child rice bowl, aka a parent and child bowl. The parent is a chicken. The child is an egg. So, this is a chicken and egg donburi, basically.
The reading is 親 and 子 and 丼 combined together into one sick parent and child meal. Just think, that egg could be that chicken's child. At least they're together.
