Californian Windpipe

The Californian Windpipe is a maneuver in which a female (or sometimes a male) puts any sort of flute, piccolo, wind blown instrument into either:

exhibit a; the vagina

or

exhibit b; the ass.
They then proceed to fart/queef and perform a somewhat artistic piece of work.
usually followed by excessive cleaning of the instrument,
or if it isn't theirs, placement back where it came from.
very difficult maneuver with very few masters.
