Gaa-Gew! Is a word that is used to replace the word "Good God" when around small children or when you just dont want anyone to understand what the heck your saying because of something silly or ridiculous they did! My sister came up with this word because she is a Kindergarten
teacher and when the
kids have those "good god" moments she couldnt say "good god" in school, so she had to come up with something fun so the
kids wouldnt understand what she was thinking or saying!
