Here is just a guess: Paşa is the nickname of a little cute boy who hopefully will be dressed in black suits like a little bridegroom in the wedding ceremony of the sender and the receiver of this text..

thanks a lot^^

You are so sweet my dear... I hope Paşa is going to be little groom in our wedding.

As scalpel said, they call that little boy Paşa (means general).
