Changing the name of the Home folder?

Hi there MacHeads! =D

I need some help on changing the Home Folders name if it's even possible?
It doesn't look so, and I'm stuck with a really bad name, because it just took my email, and I didn't think my 'Short Name' would matter. I'm able to change the short name, but not the home folders name.. Does anyone have some trick?
Idunno, a buried source file or a terminal command. Please 😕

Woah o_o
Didn't know it was such a big deal.. I won't mess up my system, so I guess I'll live with it. >_>
Thanks for the quick response! 🙂
