So I had a friend a loooong time ago who used to call her little sister "Nunu" (stylised wither Nunu; Nuu Nuu; Nu Nu or Nu-Nu I'm not sure which). It was short for something but I don't know what it is.
Looking on Facebook, there's actually a lot of results with "Nunu / Nu Nu / Nu-Nu" but I'm sure half the accounts are fake (profile pics as naked as you can be without being banned) and the other half appear to be foreign (mostly Asian) or at least a race that isn't White British. My friend was White British and I'm sure the name was not of Asian decent (I could be wrong though, I'll admit)
Does anybody have any ideas?
