The 'Upset Because of a Certain Someone, They Know Who They Are' meme is the ultimate embodiment of 'vague-booking'—the act of posting a cryptic social media status meant to provoke concern or call out an individual without identifying them. While the phrase has existed in the digital lexicon since the early days of Facebook and MySpace, it evolved into a meme template featuring various frustrated characters, from SpongeBob to distraught celebrities. It humorously parodies the performative nature of online drama and the passive-aggressive way people handle interpersonal conflicts. Today, it is widely used as a relatable joke about minor inconveniences or as a self-aware nod to being 'extra' when things don't go your way.
