Whatcha Thinkin Bout? is a catchphrase and image macro series in which the subjects are typically laying down with their hands on their chin in an inquisitive pose. Additional frames are sometimes added with "Nothin, just X stuffs" as a reply.
One of the earliest known images comes from a photo of a man wearing a keffiyeh that was posted to the Arabic Graaam forum on August 12th, 2007. The first known instance of the image with the "whatcha thinkin bout" caption was published in a post on the web culture blog UpRoxx on August 5th, 2010.
On October 1st, 2010, the original image was submitted to Reddit by user neuralstate in a post titled "Hey Reddit…" Redditor dkrainey replied to the thread with a photo of himself in army fatigues saying "I have the perfect companion for this picture" and Redditor selectrix replied with a combined version of the two photos captioned with "Whatcha thinkin bout / Oh, I dunno.. war stuff, I guess." The next day, the image was submitted to the viral content site BuzzFeed and was resubmitted to Reddit by user BigDangDude, receiving 5,321 up votes prior to being archived.
