Ginormica is the codename for Susan Murphy in DreamWorks Animation's Monsters vs. Aliens, released in 2009 and voiced by Reese Witherspoon. After being struck by a meteorite, Susan grows to enormous size and joins a team of monsters held by the government. Short vocal clips from the film, including grunts and groans, later circulated on soundboards and in fan edits as standalone reactions. This groan remains popular because it is brief, clearly expressive, and easy to drop into edits without dialogue explaining the mood.
