The 'Oh My God, They Were Roommates' meme originated from a viral 2014 Vine by Matt Post, featuring a woman talking on her phone while walking down the street. After overhearing her mention '...and they were roommates,' Post repeats the line in a dramatic, hushed whisper. The clip became an instant classic, eventually evolving into a cultural shorthand for situations involving thinly veiled queer relationships or 'historically close' friends. It is widely used across Tumblr, Twitter, and TikTok to poke fun at the trope of historians or news outlets downplaying romantic partnerships as mere roommates. The meme remains a staple of internet culture for its perfect comedic timing and versatile application to pop culture fandoms.
