I know I've already forgotten some of the mispronunciations out of the mouths of my children. Here's just a few I can recall at the moment:
Billabar - meaning, boulevard
Skush - discuss; as in "Do we have to skush about it?"
Callipitter - caterpillar
Daddy Town - as in Gatti Town (children's pizza joint)
Billabar has already ran it's course, so has skush. Callipitter is still around. Daddy Town just won't go away.
I'll miss those words.
Let us know some words you've heard. I hope it will jog my memory for others I've heard.
