First time reading that word(?) or name (?).
Well. From a quick search this looks like a useless joke application. If you want to call a page full of intentional speeling errorrs funnnie. I have no idea what it does.
As for the question "Can it brick the 3DS?": That is an inherent problem with software modding consoles. Via exploits we get full access rights and can damage the OS, which we are not supposed to. Of course console malware is possible, but thankfully it does not (yet?) seem to be a widespread issue.
The source code does not look too complex or long.
I could run it on my test console.
