Denim Shackles

Also known as jeans...but not ordinary jeans. Denim shackles usually appear while having sex standing up and your pants are around your ankles, binding you much like leg shackles.

Guy 1: "Dude, I was about to bone my girlfriend when I tripped over these denim shackles and she was like 'there is no way'."

Guy 2: "Dude, that blows!"
