We Don't Do That Here
We Don't Do That Here is a memorable quote uttered by the character Black Panther (played by Chadwick Boseman) in the 2018 Marvel superhero film Avengers: Infinity War. Online, a screen-capture of the character saying the line has been used as the punchline to jokes about social faux pas, both real and absurd.
On April 27th, 2018, the film Avengers: Infinity War was released in theaters in the United States. In the film, the characters Bruce Banner and James Rhodes (played by Mark Ruffalo and Don Cheadle, respectively) arrive in Black Panther's home in Wakanda. When Banner attempts to bow to Panther, who is the king of Wakanda, he responds, "We don't do that here" (shown below).
About two weeks later, Tumblr user she-writes-love posted just a screen-capture of the line being said with the caption "When Writers™ have entire notebooks filled and detailed outlines and know what the fuck they’re doing. And then they ask what your preferred method is and you respond:" The post (shown below) received more than 4,100 notes.
The following month, Twitter  user @slutparadies posted a mock version of the reaction with the caption "When you're from Alabama and want to marry outside your immediate family." The post (shown below) was shared later that day on the /r/dankmemes subreddit by Redditor MyDixyRekt2. The post on /r/dankmemes received more than 5,500 points (96% upvoted) and 30 comments in 24 hours.
Over the next 24 hours, Redditors on /r/dankmemes continued to share variations of the meme (examples below, center and right)
