If you have ever received a text or comment with the letters “MF” and paused to figure out what it meant, you are not alone. This short abbreviation shows up everywhere, from casual chats with friends to comment sections on TikTok and Instagram, and its meaning can shift completely depending on who sent it and how it was used.
