Put away the blue and black dress — or was it white and gold? And leave behind Yanny or Laurel. Here’s the latest debate to grip the internet: Should you recline in your airplane seat?

It all started after a woman posted a video on Twitter of her in a reclined airplane seat. A man seated behind her rhythmically pushes the back of her seat at least a dozen times, the 45-second clip shows. The video shows the man’s tray table was down, with his phone resting on it.

“He was angry that I reclined my seat and punched it about 9 times — HARD, at which point I began videoing him, and he resigned to this behavior,” the woman, Wendi Williams, wrote on Twitter.

Ms. Williams said the pushing continued throughout the roughly 80-minute American Airlines flight from New Orleans to Charlotte, N.C., on Jan. 31. The man in the video has not been publicly identified.
