Edmund: Certainly not. I just think that more could be achieved by giving them some real toilet-paper.
This trope is when literary writing is seen as such poor quality that it's only fit to be used as toilet paper or campfire tinder, (or similar undignified uses).
Sometimes it really is that bad, but a common variation is an illiterate or less cultured person using a book for toilet paper or kindling because he genuinely can't see any other use for it. In this version, don't be surprised if the book was a gift from an intellectual character.
This is often a comedy trope, but not always. Saying another person treats a given text like toilet paper can be serious, depending on how serious the text in question is. A politician who says a rival "may as well be wiping his rear with the Constitution" is asking for a fight.
If the text in question is real, there's often an element of Take That! present.
Before the availability of cheap purpose-made toilet paper, people commonly used old paper for wiping purposes. The rural outhouse with last year's mail-order catalog hanging next to the seat is Truth in Television, but not this trope because the catalog had value, it's just on its final cycle of usefulness.

- CHERUB: In one book, two CHERUBs on a training mission in the wilderness are given knapsacks filled with seemingly random supplies, including an apparently useless copy of The Complete Works of Shakespeare, which they leave on the beach they were dropped off at. It's only later, in the jungle, that they realize the book was included with the intent for the pages to serve as toilet paper.
- There's a couple of references to this in Discworld. It's indicated that the only book Cohen the Barbarian had ended up as toilet paper.

- In the Sven Hassel novels, Tiny's mother ends up using the Your Fuhrer Thanks You card she got notifying her that one of her sons had died 'fighting bravely' for Nazi Germany.

- Spongebob Squarepants: In the live-action segment of the episode "Party Pooper Pants", Patchy the Pirate tried to invite Spongebob and Patrick to his party via invitation. The problem is that they can't read it because the ink smears underwater, so they threw it in the campfire. Underwater.
