You might be thinking of Ghost 1.0. According to the Developer's Foresight page:
...you're prompted to enter your name and advised to "choose wisely, as it can't be changed later". If you type "wisely", the game responds "Ha-ha, very funny" and quits to desktop. If you enter "changed later", the game reminds you that your name can't be "changed later" and tells you to "type another name". If you type "another name", the game expresses its annoyance and quits to desktop again.

All I know about it is that in the naming system has something to the effect of it asking you to type a name and you literally typing "a name" or something along those lines and it says "Very funny, pick another name"
