Phrase used to sarcastically acknowledge someone's contribution to a conversation or action that ultimately has little to no impact or relevance. Originating from the movie "Raiders of the Lost Ark," it refers to the overall premise of the film, where Indiana Jones's involvement does not significantly alter the outcome of events.
Person A: "I just read an interesting article about the latest advancements in renewable energy technologies."
Person B: "Oh, my cousin once visited a wind farm on vacation."
Person A: "Thank you Dr. Jones. Your fascinating family anecdotes truly elevate our understanding of renewable energy advancements."
When used with a screenname, a good way to point out a probable troll. Especially useful in a long comment war, when you can see that people are taking things way more seriously than they were probably intended.
