This viral home video, which gained massive traction on YouTube around 2011, features an unnamed infant and their father engaged in a hilarious cycle of emotional whiplash. The scene depicts a classic 'reaction' dynamic where the father enthusiastically shouts 'Yay!' to encourage his child, only for the baby to immediately burst into tears at the sound. As soon as the father stops, the baby resets to a neutral or happy state, creating a loop of instant distress and recovery. This clip is a staple of early 2010s internet culture, representing the 'wrong' reaction to positive stimulus. In the meme world, this template is the gold standard for representing a person's visceral hatred for forced positivity or 'toxic optimism.' It is frequently used to mock corporate enthusiasm, unwanted social invitations, or the feeling of being overwhelmed by someone else's high energy. Example captions include: 'Me when my extroverted friend says we're going out tonight' and 'When the boss says we're having a mandatory team-building exercise.'
