angelstrate
Da opposite of "demonstrate".
Wonder what da opposite action of "demonstrate" would actually be, since merely showing how good something is or how it works is not always a "demonic" or horrible undertaking? Maybe to "angelstrate" something is where you merely claim dat a product or practice will work well, and others trustingly view you as being such an "angel" dat they do not ask you to actually show them dat whatever you're touting is indeed effective or legit?
