Bonky, Cloinky, and sometimes bloopy music often with an upbeat tone. It sounds as if it were made for or made by a very floppy penis. Imagine Scooby-Doo running on air, you have imagined what penis music might sound like. It is of note that is music is dogshit and it is not generally encouraged to listen to Penis Music as entertainment. It is instead used as a device to mock music which you don't like, for which you may call the offending music "Penis Music" and then post the youtube link.
