Usmay be Sororitya work of horror, but this Instagram post is pure fun.

Lupita Nyong'o shared a video on Friday featuring the four main stars -- Nyong'o, Winston Duke, Shahadi Wright Joseph, and Evan Alex -- each rapping a verse about their characters. A beat playing in the background remixes the movie's updated version of "I Got 5 On It."

"Troublemaker ain't scared of Us," the caption reads.

The music and rhymes are from Chris Herbie Holland and Robyn Hood (aka Miriam A. Hyman), respectively, as Nyong'o shouts out in her post. You can hear a longer version of the track, sans movie stars, on Robyn Hood's SoundCloud page.

Us hit theaters on Friday. The second big screen effort from director Jordan Peele (after Get Out) follows the Wilson family, led by Nyong'o and Duke, during a summer vacation from hell. Their worlds turn sideways when a family of apparent evil twins shows up in their driveway one night. But who is evil, really?

Each verse in Robyn Hood's rap references the Wilson family's doppelgängers, including their look, their lines, and their overall vibe. In the video from Nyong'o, the four stars each tackle their own character.
