The Oscars ended in a figurative dumpster fire Sunday night, with a historic screw-up closing out the show.

Across Facebook and Twitter, people can still hardly believe the "Best Picture" presenters announced the wrong winner.

Social Cues is our look at what is trending across social media. Here's what people are talking about Monday:

Oscars: This year's Academy Awards outdid Steve Harvey's Miss Universe fiasco in 2015. The prestigious awards show ended with a plot twist as the Best Picture presenters accidentally named "La La Land" instead of "Moonlight." The producers apparently handed Warren Beatty and Faye Dunaway the wrong envelope. The memes have been racing across Twitter since then, with #envelopegate and #OscarFail trending. Oscars host Jimmy Kimmel earned his own Twitter moment after tweeting at President Donald Trump during the show, netting more than 238,000 retweets.

#MWC17: The Mobile World Congress 2017 is just kicking off, and CNET's team is on the ground in Barcelona. The hashtag for the annual mobile extravaganza is trending worldwide, offering a glimpse of the phones and wireless gadgets that companies hope you will soon be scrambling to buy.

Nokia 3310: The classic handset has returned from the grave, though a lot has changed in the 17 years since the Nokia 3310 was originally released. Noted for its month-long battery life and durability, Nokia showed off the nostalgia-fueled phone at Mobile World Congress on Saturday. The device is still trending across Facebook. We got our hands on one and, yes, it has Snake.

Rachel Dolezal: She made headlines in 2015 for pretending to be African American as she became president of the NAACP branch in Spokane, Washington. Her biological parents revealed the truth, showing childhood photos of her as a blond, white girl. She's trending on Facebook on Monday after Dolezal told the Guardian that she's on the brink of homelessness and still faces public ridicule. Folks on Facebook are divided, with some feeling sympathy for her current circumstances and others arguing that she deserves it.
