What ARE these reviewers (myself included) talking about?

An old friend sent me a clip of people taking the piss out of wine analysis. Firstly it made me laugh then it got me thinking why do they talk they talk like this and what are they saying or they don’t really smell that they are making it up. Then I realised I talk like this and I say these then thanks @nancy_tschetner_artist for sending me this clip (below) and giving me a great topic to dive into.https://www.instagram.com/reel/DJJi4foNBi5/?igsh=MXEzM29wanNweHpwZQ==
