Troy McClure is a recurring fictional television host on The Simpsons, voiced by Phil Hartman, famous for introducing himself with his film credits. The phrase in da house comes from 1990s hip-hop slang for announcing someone's arrival, and it became a staple of DJ and party introductions.

It spread through meme soundboards where short Simpsons voice lines are shared for edits, streams and reaction videos.
