What does "fam" mean on social media?

Fam is short for “family,” but it’s often used more loosely to refer to close friends or people in your inner circle. It’s a term of endearment, usually directed at people you consider to be like family, even if you’re not related by blood. 

Originating from African American Vernacular English (AAVE), “fam” is a common feature in casual conversations, especially in texts or social media, when people are addressing their close friends or followers.

For example, you might say, “What’s up, fam?” when greeting a group of your friends. It’s a warm, friendly way of acknowledging the people you’re close to. It’s become popular in online communities and among younger generations as a way to create a sense of closeness and community, even in digital spaces.
