Aw jeez became Morty Smith's best known catchphrase across Rick and Morty, the animated series that premiered on Adult Swim in 2013. Morty's anxious delivery made the short line easy to clip and reuse outside the show. It spread through reaction videos, edits and soundboards as a shorthand for nervous dread. Fans associate it instantly with Morty being dragged into another risky adventure, and its brevity keeps it popular for quick comedic timing online today across social media, streams and fan made compilations shared widely.
