The "Waiting for OP" and "OP will surely deliver" memes typically consist of image macros showcasing people, animals, or skeletons seated before computers, suggesting they've been waiting indefinitely for the original poster (OP) to respond. These images communicate a humorous skepticism or cynicism about the likelihood of the OP returning to the discussion thread to fulfill a promise, such as providing evidence or elaborating on a story.
The term "waiting for OP" originates from a post on the Democratic Underground forum dated March 3rd, 2005. The first notable use of the phrase "OP will surely deliver" in an image macro featured a reclined skeleton and appeared on the image hosting site Chan4Chan on December 29th, 2009. The image is used to humorously convey doubt that the OP will return to the thread to provide promised information.[1]
