"Oh s---. I'm a f------ re----," Zae said, before adding, "D—, I shouldn't say that word." "No, you shouldn't," Keanu responded, in a video captured by the outlet. "That's one of the ones I was working on not saying," Zae later noted. The pair then laughed it off before Keanu told him, per TMZ, "I think you're good … you're lucky it's late." However, several people responded to theBig Brotherincident onX, with one person writing, "When did it become OK [to] throw that word around again? It's everywhere again." Another userjoked, "Now CBS gonna have to address it." CBS Another wrote onX: "Well, that escalated quickly. Who knew reality TV could go off the rails so spectacularly? Classic 'Big Brother' drama." The slur in question is a hurtful term, which was originally introduced to "define people with intellectual disabilities," but in the decades since, has "become an insult used all too commonly in everyday language," according to theSpecial Olympics. "Those who use the R-word often do so with little regard for the pain it causes people with intellectual disabilities—and the exclusion it perpetuates in our society," Special Olympics continued.
