The "Marked Safe From [Big] Today" meme is a humorous adaptation of Facebook's "Safety Check" feature, which allows users to mark themselves safe during real-world crises. In this meme, people ironically declare themselves "safe" from a mundane yet overwhelming daily event or concept. Users fill in the blank, often with things like "Monday," "responsibilities," or "emails," expressing a shared sentiment of relief or exhaustion after surviving a particular challenge. It typically conveys a lighthearted sense of overcoming a daily struggle, often with a hint of sarcasm or ironic detachment, making it popular for commiserating about everyday stressors.
