Goo

While me and Alex were driving around in his truck yesterday We had this conversation

Alex- Hey Boo
Sasha- Whoa did you really just refer to me as the name that a "certain group of people" give their boyfriend or girlfriend?
A- Hahaha why yes i did
S-.....Well how about lets not
A- Hey if I was your boo wouldnt you be my goo?
S- Hahahaha I dont know
A- Come here goo!

So here is a question. If a boyfriend is a boo, wouldnt a girlfriend be a goo??
