Well.. I'll try to clear things up to you.
1. You find your name on the internet (google etc)
- If there is no result, you make a new homepage, with some violent stuff and tell the GM's that you don't want to be related to that. Its quite simple.
If your name is;
"Pikmin" then you ask for a name change, since is "Pik" is "Dick" in danish and "min" is "mine" in danish..
You gotta make a context to relate to.. Tell them that you don't want people to relate stuff to your name..
