Yes, I could see this sentence being used that way too. Flag it if it's not yet accepted. :)
By the way, literally translated "kulta" means "gold". Other kulta-related pet names include "kultaseni" (kulta+nen+ni - my little gold), "kullanmuru(seni)" (my small crumb of gold) and "kullannuppu" (goldenbud). "Kullannuppu" is used of children, sometimes a bit sarcastically.
