An event wherein a certain tune, played on bagpipes, is so beautiful that a male who is listening to the tune experiences an erection. Also defined as a Piperection, bagpipe boners are more common in enthusiastic male bagpipers, all sexuality aside.
"Dude, I was listening to Scotland The Brave and got a total Bagpipe Boner."

"Wow, you'll get hard off anything..."
