The "Thank You For Coming to My TED Talk" meme is typically used on social media to conclude a monologue or personal opinion that resembles the style of a TED Talk presentation. It is often employed humorously to add a formal or grandiose finish to a trivial or detailed exposition on any topic.
The meme has its roots in the BBC Sherlock fandom, first appearing on Tumblr. On May 28th, 2015, a Tumblr user with the handle beysuspng reblogged one of their earlier posts, which included a commentary on characters John and Sherlock from the BBC television series. This reblogged post contained the phrase "Thanks for coming to my TED talk," a parody of the concluding remarks typical at TED Talks. More information about its origin can be found here.[1]
