"Peele says that he considered a whole bunch of titles before settling on Get Out. 'I think the first working title was Get Out of the House,' he explains. 'Which was just a longer sentence that one might scream at a typical horror movie. At some point, probably in the tradition of Scream and some of the pulpier horror movies from the 1960s and ’70s, I went with the exclamation point. Well, I didn’t go with the exclamation point, but that’s implied. At some point, I was toying around with horror titles that were a little bit more on the nose. So I was thinking about the title Keepers. And at one point I even thought about calling the movie White, but nothing ever beat Get Out.'"
"In Get Out, the opening title sequence plays over an ominous song by composer Michael Abels called "Sikiliza Kwa Wahenga." Fusions explains that the title means "Listen to (Your) Ancestors" in the East African language of Swahili, another reference to slavery and racial identity. Peele stated to GQ Magazine that he wanted the music to be "distinctly black" and with an "absence of hope." The lyrics reveal even more; after chanting "Brother, brother," in English, the Swahili lyrics translate as a warning, loosely "Something bad is coming. Run!" It's an affirmation of the title Get Out and the foreboding sense that something bad is going to happen. According to Peele, it also reflects a tradition of African-American viewership to talk back to movie screens during horror movies, admonishing characters for taking actions that put themselves in danger rather than just getting the heck out of Dodge."
So he was evidently referring to the black community in the previous quote about screaming at horror movies.
