What is Thunderbox?
1.
A toilet
This is Australian slang
It is called a thunderbox because sometimes when you go to the loo you fart, and it sounds like thunder. I don't think I have to explain the box part.
Ah that felt good! I did a big one in the thunderbox just now! Boy it smells!

A box built for shitting in. Often found on campsite grounds.
I really let loose with a storm of poop on the thunderbox.
