Perhaps, but there are definitely people who just stick in a string of verbized/adjectivized nouns in order to sound sophisticated or intelligent. In reality they just sound like they are full of hot air.
It's one of the many reasons people are so put off by salesmen.
Totally agree. A lot of technical people miss this. Sales people often (but not always) do this because they don't understand the product - they tend not to have a deep technical background. They compensate by picking up the language - most sales people spend a lot of time in conversations with other customers, product managers and technical people where a range of words are used. It lets them pick up the words, and get a shallow understanding of the concepts.
So most commonly you should just assume the sales guy is confused rather than being a tricky genius!
