The first time I tried karaoke, I was a bit intoxicated and worried that, having a common name, another Nick would get confused. My parents worked by full name incorrectly, so, I figured that that would be a great way to differentiate it, not realizing at the time that the name “Nick” itself normally has a “k” in it, making “Nick w/ a K” arguably more confusing. After sobering up, I found the whole concept wonderfully silly and decided to switch to it as my main screen name.
