Some funny words are when you hear what animals say in other languages. In English, we think a dog says "bow wow" or "Arf Arf". A cat says "meow", a rooster says "cock-a-doodle-do", a chicken says "cluck cluck" and a duck goes "quack-quack". A cat can also "purrrrr", and a mouse "squeeks". When you ask foreigners what the animals say in THEIR language, and they mimic them, or spell the sound, it is quite hilarious.

I think of the word "munchkin" meaning small and cute

Gobbledygook or gobbledegook which means words that hard to understand.. I knew it from a song by Sigur Ros by the way :)
