That means “nerve saw” or annoying person. And heaven knows that Claudia Roth of the German Greens has spent an entire career making a name for herself in that department.
The Frankfurter Allgemeine Zeitung even once referred to her as the “Mother of All Nerve Saws.” But that was then and this is now. She has clearly mellowed out now that she just turned 60 (today). Now it’s more like she just gnaws on your nerves.
Happy Birthday, Claudia!
Selbst Etiketten wie “Mutter aller Nervensägen”, wie die “FAZ” einmal schrieb, ärgern die streitbare Politikerin nicht. Im Gegenteil: Im Bundestagswahlkampf 2013 griff sie das Thema selbstironisch auf, eine Parteikampagne für mehr weibliche Mitglieder warb mit dem Spruch: “Wer nervt mehr als Claudia?”

She’s only “green” because Red isn’t Red enough.
Eine alte Säge ohne Freischnitt — sie klemmt, wird aber schnell Rot.
Before she went into politics she was manager of the fabulous Ton Steine Scherben (and their singer, Rio Reiser), and for that she can be as annoying as she likes (she certainly tries her best…).
Yeah. I really liked König von Deutschland. But I guess everybody did.
