Can someone tell me what Tarkan means when he sings - "kuzu kuzu"
I'll be grateful

it means
come without a word of protest

kuzu means "yearling lamb" or "hogget"? something like that.

But kuzu kuzu is a behavior like a sheep. Something like "obey" or "behave without a resist"

Tarkan says: "kuzu kuzu geldim"
means: "i came without a resist" or "i am here for your orders, i wont resist you, i am yours" etc. Because he thinks that he made a mistake so he wants to be forgiven.

That's the meaning of the song.

Let's watch the clip.
