親バカ 

I first heard this phrase at a middle school in Japan.  The students entering a school play pointed at their respective parents sitting in the stands and said to me, 「親バカ」.  Naturally I was a little appalled at hearing school children call their parents fools.  I mean, these were THE good kids.  Seeing the horror on my face and a flash in their minds of me running to their parents tattling 'Your son called you バカ!' they quickly said 'クレイ先生 - dictionary, dictionary'. I pulled out my good ole Canon IDX-9500 and calmed down.

 Kenkyusha's huge J-E says this:

おやばか「親馬鹿」     foolish [blind] parental doting

 And then it goes on to give five example sentences which accurately describe what Yumi and I have become over Makoto!
