Clay Davis is the corrupt Baltimore politician played by Isiah Whitlock Jr. in HBO drama The Wire, which ran from 2002 to 2008. His elongated sheeeit became the character's catchphrase, delivered whenever a deal, bribe or setback exposed the city's broken system. Whitlock leaned into the line's popularity in later appearances, and clips spread widely online as a shorthand for political sleaze. It remains a staple reaction sound because one stretched word captures disbelief better than a full speech.
