bag piped 

To lean over, compressing your abdomen, stimulating the realease of gas (either burp or fart).

Can possibly be done to someone else.

I dropped my pen under the desk at work and totally bag piped out a fart in front of all my coworkers.

Bag-piped 

When a man or woman picks up another man and holds him like a bagpipe while sucking his dick.

Did you see how Matilda bag-piped Johnny? What strength she had to do that.

Gillen Bag Pipe 

While doing doggy style you reach around with one hand and fiddle the vagina and with the other hand play with the breast.

Mom told Ally that last night Dad did me doggy style while fiddling with my vagina and playing with my boob. He called it the Gillen Bag Pipe.

bag pipe 

Screwing a chick in her arm pit. Similar to a titty fuck.

Damn I wish she had done a better job of shaving before I bag piped her.

Dusty Bag Pipe 

the process of spreading the female buttcheeks and giving it oral pleasure with tongue and air blowing actions. All while giving the female pleasure in her vagina via the hands and fingers. These actions combined resemble playing the bag pipe. And since anal oral can be messy, the bag pipe is indeed dusty.
The male on female equivalent of a rusty trombone.

Savannah always craves the dusty bag pipe after she goes down on me.
