Gajunking - Using a nail file on your junk and then sticking it in a pot

Using a nail file on your junk and then sticking it in a pot of screaming hot oil.

I gajunked my brother and now he thinks he’s a chicken.

My uncle gajunked his nephew and the kid ran out screaming.

I gajunked my pet rat and it hissed at me for a week.
