I heard someone use the slang term “FAFO” online or in conversation and wondered what it means. You’re not alone. “FAFO” is a popular internet acronym that’s gained traction across social media, memes, and texting culture.
While it might sound funny at first, its meaning carries a bold message often used in confrontational or confident contexts. In this guide, we’ll break down exactly what FAFO stands for, how it’s used, and why it’s become such a viral part of modern slang.
What Does ‘FAFO’ Mean?
FAFO is a slang term that stands for “F–k around and find out,” used when someone finally sees the consequences of their actions. It conveys the simple message that actions have consequences.
The term is similar to other phrases like “if you mess with the bull, you get the horns” or “stir a hornet’s nest and get stung.” Basically, if you’re creating issues or trouble, you’re going to see the bad outcome that’s heading your way.
Is FAFO Political?

FAFO has become increasingly visible in recent years, particularly during the 2024 Presidential Election. Two notable uses of the term appeared in the news cycle before and after the election on November 5th.
Philadelphia District Attorney Larry Krasner used a censored version of FAFO in a press conference referring to anyone who had plans to interfere with the city’s election process. After the election, when Donald Trump won, former Democratic congressman Bakari Sellers used FAFO on CNN’s This Morning Show to discuss how voters might face unexpected consequences.
Before the 2024 election, FAFO was popularized in 2022 when it was announced as the word of the year. The term gained significant attention when Elon Musk tweeted those four letters in response to Kanye West being removed from Twitter for sharing problematic content.
Where Did ‘FAFO’ Come From?
FAFO can be traced back to 2007 and originated from AAVE (African American Vernacular English). Like many slang terms, it emerged organically from this linguistic tradition. The term has roots in biker terminology, which provides insight into its original context and early usage.
Why Is FAFO All Over TikTok?
Although “F–k around and find out” and FAFO have existed for quite some time, the term exploded in popularity on TikTok following the recent election. Some users employ FAFO to highlight voter behavior and misinformation, while others use it to discuss how Trump’s policies might affect tariffs, imports, and the economy. Many are also using it as a response to people experiencing family conflicts over political differences resulting from the election.
Is FAFO Military Slang?
Yes, this slang term has been used by military personnel for years. It’s a popular term in the r/Military subreddit, and FAFO military merchandise is widely available.
The term has become a confident calling card that conveys a tough “don’t mess with me” mindset and is often used as a form of camaraderie within military culture.
How To Use FAFO?

FAFO is not a slur or derogatory phrase (unless you object to profanity), and it’s not confined to any particular group or demographic. People from all political parties, backgrounds, and situations have used FAFO.
The acronym works best in written social media posts, such as captions or on-screen text. However, saying “fa-foh” verbally has also become common, especially in recent TikToks. If you’re making a video, you can simply say “F–k around, find out” or use the acronym in captions.
