A poor quality potting medium that makes a gardener wants to facepalm e.g. unprocessed palm soil.
1. This muddy clay-like plant medium is such a facepalm soil as it will turn into a brick hard soil when it dries.

2. I was forced to mix up the facepalm soil with 50% paddy husks in order to make it dry enough and give it a good irrigation.
