A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
Almost none of this applies in the case of something like loop quantum gravity, which I understand very little of but I don't believe it's possible to discuss it using the language of QFT like I have above.
