Hagedorn
When you dip a cigarette filter in your pee and then stick it back in your friend's pack, and they taste the salt and make a face like they just saw a dead rat.
I dipped a cigarette in my pee and stuck it back in my friend's pack. He took a drag and made the saltiest face ever.
My buddy did the Hagedorn move and his friend coughed out a lung and a tooth.
I did the Hagedorn and my friend tasted the salt and cried like a baby.
