I think we all know where this is going refers to a popular quote turned reaction image from the cartoon series The Amazing World of Gumball.
The reaction image is used online as a reaction image macro, paired with headlines and titles that foreshadow the ending.
The phrase was first heard in Season 4 Episode 6 of The Amazing World of Gumball, titled The Check, which first aired on August 31st, 2015 in the United States.
The episode features Gumball becoming the President of the world, which results in a robotic uprising or a “robolution”.
President Gumball then makes a declaration in the Oval Office, saying “My fellow Americans, I think we all know where this is going so let’s just skip to the end”.
“I think we all know where this is going” would later become the caption of the reaction image, depicting Gumball in the Presidential Office.
The meme would appear on a number of sites, starting in 2016, both as a reaction image and as a standalone catchphrase.
“I think we all know where this is going” could be encountered on sites like Reddit, Imgur, YouTube as well as Facebook, Twitter and Instagram.
