I think the OP is German, and in an attempt at humour, called HIMSELF. A Kraut.
I was surprised, as you, as I was brought up, that it was an insulting term and not to be used.
However, if someone wishes in humour to call themselves it, its fine. I'm inbred (where I spent the longest part of childhood was often referred to) taffy, Mick, paddy .
But, if.you want a reply, best to call me, Mac!
