Is ahpunehneh a proper word?

For your own safety, refrain from using ahpunehneh...

I seriously had enough of all your "ahpunehneh" rubbish, holding noses and all racist acts. And parents, if your kid points and says "ahpunehneh", correct him/her. Don't you freaking ignore it or worse encourage it. If i see one more kid look in my general direction and say "ahpunehneh", i will throttle him/her til he can't remember the rubbish ever again. I swear i will do it. Because i had enough. - Frozenqueen
