Gajunking
Taking a rusty cheese grater and rubbing it against your peen before dunking it in a pot of hot grease.
My cousin gajunked himself in the garage and now he smells like burnt French fries.
He tried to gajunk me with a rusty spoon and I still have a scar on my junk.
My mom said I had to gajunk my little brother before he could eat pizza again.
