2. What does BFR stand for?

Be for real

BFR is slang for when people think someone is exaggerating, being unrealistic, or saying something hard to believe. It's basically a shorter, punchier way of saying "seriously?" or "you can't be serious." The phrase itself has been around in spoken conversation for years, especially in Black American English, but the BFR shorthand became especially popular in the 2020s through TikTok, texting, and social media.

Today, teens, young adults, and online communities commonly use BFR in comments, group chats, and memes. It can be playful, sarcastic, or mildly confrontational depending on the tone, and you might see it when someone reacts to a wild opinion, an unbelievable story, or an overconfident statement.

Example
