Years ago I called my baby brother Pipsqueak, my mother got angry, told me to look it up.
I did. It meant insignificant person. I loved and adored my baby brother, so I stopped calling him the icky word.
Today I find out, pipsqueak means much more.

It's also related to WWI medals awarded in England. And cartoon characters.
I thought it meant cute, little and adorable. I stand by my first assumption.
Love you Pipsqueak!!
