Midieval Bag pipes 

This is when you are dressed up in full midieval attire (knight armor, renaissance clothes, kings, queens ect...) and are getting head from a chick, while you move the handle of your sword in and out of your ass.

At the last renaissance fair, Lady Marrion and my self had a lovely time playing the midieval bag pipes....
