Awful. What is with all these prim, effeminate names people keep giving their boys? To be unique like all the other Orah book watchers? Very few people can pull off a "Tobias" or "Florian," even with the inevitable dopey nickname. Stick with something that won't get your kid punched in the face, please.
Tobi is a perfectly common man's name in Germany It won't get anybody looked at oddly or punched in the face.
I always thought Florian is ugly, though. It was fashionable(-ish) around the time of my birth as well. The common nickname is Flo (pronounced the same as Floh, "flea").
