Davis popularized the phrase “Sheeee-it!” that became a viral meme on social media.

“I did it there, and I did it in She Hate Me,” Whitlock said in a 2008 interview. “But then, when I got on to The Wire, I saw a couple of opportunities where I could do it, and I did. And they started writing it in.”

His first TV role was a 1987 guest appearance on CBS’ Cagney & Lacey. He also appeared in multiple Spike Lee films and roles in such TV series as Veep, Your Honor and The Residence.
