oh that’s not- 

oh that's not- refers to a memorable line said by a co-host from The View program in 2015 after Kelly Osbourne tried to call Donald Trump out for his offensive remarks about Latinos being murderers and rapists. While co-hosting on the show, Osbourne made a mistake by saying, "If you kick every Latino out of this country, then who is going to clean your toilets, Donald Trump?" to which a co-host responded, "oh that's not-" This moment became a popular reaction video & catchphrase on twitter, tiktok & irl, often used to describe racist, offensive, annoying, weird, unfunny behavior on social media.

Example 1

Person 1 : wait y’all wash your legs???

Person 2 : oh that’s not-
