Turned out in Croatian, a 'Peder' was someone with an unhealthy interest in kids.
Poor Peder immediately got ruled out as dating material - no way she'd be able to bring a guy back to her parents and introduce him as, well, a pederast.
(My name, too, is somewhat unfortunate in the anglo world - first name being 'Odd'. Oh well. There's a couple of Norwegians having it even worse. One of them is actually named just that. Even Worse. (Not to mention the brother of another former colleague, named Odd Male.)
