When you smother peppers on your penis until it burns and your compadre then blows on your cock, like blowing a flute.
What you call a girl that gave some head to one of your musical friends.
"Dude last night I was getting off with some peppers when my girl came up and blew on my dick, what a Peter Piper!"
"Hey, Jessica gave Jimmy some head last night."
"Really?"
"Yeah, she's totally a Peter Piper."
