Overly Attached Girlfriend (OAG) is a fictional character and an Internet meme originating in a YouTube video published on June 6, 2012.

The video was a submission to a contest held by Justin Bieber who challenged fans to create a "Girlfriend" counterpart to his hit song "Boyfriend".

The video, which satirized elements of the Bieber song that have been perceived as clingy, featured Morris staring at the camera with a fixed smile while singing about Facebook-stalking her boyfriend and other themes.

[9] On June 18, 2012, another video, in which the Overly Attached Girlfriend sang a parody of Carly Rae Jepsen song "Call Me Maybe", also became very popular.

[14] On June 13, 2013, she uploaded her first political video, a parody of the U.S. national anthem in which she is dressed as Uncle Sam and sings about watching you through Skype, Facebook, and Google because she "cares" but does not mention the current NSA leaking controversy specifically.

This has involved a new "attachment" to her Kia Soul,[25] comedy skits on "LifeAccordingToJimmy", reporting from the red carpet at the American Music Awards,[26] videos starring her dogs Luna and Gilly, and "Dare to Share" for charity.

[32][33][34] On September 25, 2013, Morris appeared with Good Girl Gina, Sheltered College Freshman, and Bad Luck Brian in a "Meme Hunters" commercial for RealPlayer Cloud.

[35] Despite the "Overly Attached Girlfriend" being portrayed as a crazed hopeless romantic, Morris confirmed on a viewer fan mail episode on January 22, 2015, that she was in a relationship at that time.
