Hi, Jahanzaib. It's cool to see that your username actually comes from a typo! Haha, that was unexpected!
It might be different in your language, but I'm pretty sure Xabi and Zabi is pronounced the same way in English, so it's not that big of a difference.
And I'm glad you didn't chose your real name as a username: it was much more difficult to write :P
Yeah Difficult to write and pronounce. ..lolzzz
