Not Sure What to Call this One

I was walking through a storage area at work and I came across a woman talking on her cell phone. It wasn't anything unusual except for the fact that she had a huge, steel-toed boot perched on top of her head. Like this:
As I walked by I looked her in the eye (which is kind of difficult to do when someone has a boot balanced on his/her head) and smiled. She looked back at me and stopped talking long enough to glare at me.

I got a dirty look from a woman with a boot balanced on her head.

Later that day, I walked by that same area and found the boot. I looked around and then put it on top of my head. That's when a co-worker walked by.

I didn't get a chance to explain.
