just adding that "re katsiki" is a funny friendly -most times- way for the word "silly" or "stupid".

so by calling you a goat (it's not lamb) it means you're silly as a goat is.

That's actually quite funny, but it doesn't make much sense. It is :

"Where is the photograph, you lamb? Do you want me to pick you up or do you have money for the taxi?"
