What does jinchan mean?

Question:

Some Japanese boys came to my table at a convention and started giggling to themselves, talking about my art (in Japanese), and would keep pointing to me and saying 'jinchan' in the middle of their conversations. It was obvious they were calling ME Jinchan... but what does it mean? I know a little basic Japanese (enough to work out they really liekd my pictures), but I've never heard 'jinchan' before.

Answer:

chan is suffix used for a girl. Jin must be a name. But I'm not sure.

So the bottom line is, only they know what they mean.
