pinwheeling 

When sick with the stomach flu, pinwheeling is the unfortunate act of simultaneously projectile vomiting out one end while shooting explosive diarrhea out the other. So named for its resemblance to a pinwheel firework, which emits a strong stream of sparks in opposite directions in order to spin.

"Wow, I haven't been that sick in years. I was in the bathroom all night; at one point I was pinwheeling..."

pinwheeling 

When using a Mac and your cursor become an infinitely spinning pinwheel. Often occurring when a programme crashes or when too many applications are opened/being opened at once.

While opening my Adobe software and watching videos online at the same time I was hypnotized by Mac's colourful pinwheel.

I was pinwheeling when I overloaded my Mac with processes.

Pinwheelism 

The art of being prejudiced towards a pinwheel.

As in color, shape, size, way of spinning, et cetera.

"Gosh sally! You are such a pinwheelist!"

I hate that pinwheelism, you know, the pinwheels deserve a chance.
