This is an unfortunate happening when you are receiving a blowjob from a chick that has braces and the metal rips the skin- hence a 'pecker ripper'
--Johnny is getting his cock sucked by a piece of jailbait
Johnny - Woah you are really good, the metal is an extra bonus!
chick - Mmmfff..
Johnny - Wait it's getting caught on metal.. AUGGHHH!!
hospital nurse - I guess Johnny got a pecker ripper
pulls out a bloody dick
