This legendary viral clip originated on Vine in 2014, capturing a chaotic and hilariously unprofessional moment in a high school classroom. The video features an frustrated substitute teacher reacting to a student who threw a crumpled ball of paper at his head while his back was turned. He spins around and delivers the iconic line: 'Whoever threw that paper, your mom's a ho!' with absolute conviction. The sheer audacity of a teacher using such language in a school setting turned this into an overnight internet sensation. Culturally, the clip represents reaching a boiling point and responding to minor disrespect with an over-the-top, petty insult. It is commonly used as a reaction to being roasted in a group chat or facing minor inconveniences from friends. Popular captions include: 'When the group chat starts cooking you for no reason,' 'Me to the minor inconvenience that ruined my whole day,' and 'When your siblings start blaming you for something you actually did.'
