What is a triple entendre? This is a reference to the third side of the coin.
Or a meaning which is a multiplier in a way that is hard to describe, as in, the definition is not easily communicable, and references in regards to such a triple entendre are very difficult to decipher. As an example, as a lingual haven for multi meanings, a triple entendre can be anything like an artifactualable: an artifact, an intangible, and a play on words of being plausible and possible. It is up to the reader (and the provocateur), to assist each other in sharing a correct meaning, and not all three or more substance meaningfuls.
