The phrase "most porno" does not have an established etymology as it is not a commonly used expression or term. However, it seems to be a combination of the words "most" and "porno", both of which have their own origins.
1. Most: The word "most" originated from the Old English word "mǣst", which has Germanic roots. It is related to the Old High German word "meist" and the Gothic word "maists", meaning "most" or "greatest". Over time, this term evolved in Middle English to become "most", retaining its similar meaning of the superlative degree.
2. Porno: The term "porno" is an abbreviated form of "pornography", which is derived from the Greek words "pornē" (prostitute) and "graphē" (writing).
