Thanks, it really helped. No he is not friend like that, only a work friend.
I nerver knew that people write qk instead of "kuk" in Sweden so it was quite a shock to me.
But you guys are all right, it means something to me and the majority won't read it as a word and I have to stop thinking about what he said.
The thing was that my mom and dad have not seen the tattoo so I was worried that they may missread it too.
Wow, I can't see having any stress over that. Don't worry what others think/say, if it means something to you and/or your family, enjoy it and don't worry! I'm betting that in 95% of your interactions with others it will be covered anyway.
Adopt an old man's attitude... screw 'em!
