can anyone tell me what this means, thank you, thank you to translator. i appreciate.........................

Koca olan olmuş ya

something like " who become husband had became husband"

This should be "Koca oglan olmus ya"... oglan means boy

koca means big  This sentence is used for the kids grows up

Koca oğlan olmuş ya.

Then i think it must mean: Wow, how big this boy is!

Yes, but without " WOWW"
