I’m my local dialect of Arabic we say some hilarious expressions for peeing including:

I’m going to fly some water (like flying a kite)
I’m answering nature’s call
I’m paying the judge.

My favorite term for pooping in nature when we go hiking was:

Planting a mine

It should be OK, people put blankets on the floor all the time.

But why don’t you store them in a close during the summer?
