Receipts is a slang term that refers to comments, images, video, etc. that proves a claim. The term is often used when defending a claim or pursuing the truth of a statement, perhaps to reveal the hypocrisy of a person.
The name comes from the actual use of receipts as proof that something was purchased. It is similar to a "paper trail" or the "proof is in the pudding" phrases where hard evidence is followed to a truth.
