Oh my god is one of the most reused reaction phrases online, shortened in titles to omg for quick searching and instant recognition. Clips built around the phrase spread through meme pages, reaction compilations and short form video apps, where a short stunned vocal became shorthand for any over the top moment. This longer version stays popular because the repeated delivery works for both genuine shock and ironic comedy, letting creators stretch a reveal, mock a minor inconvenience, or underline a dramatic announcement without needing extra dialogue or context.
