Where does mufo come from?


The term mufo clips and blends the expression mutual follower. The term mutual follower is seen by at least June 2007 on Twitter, where a mutual follower is someone you follow on social media who follows you back (hence mutual).

Because mutual follower is just apparently way too long for the internet, mutual follower was shortened to mufo by at least 2010.

Before the social media mufo went mainstream, mufo was sometimes used as shorthand for motherfucker or motherfucking. It’s still used that way sometimes online, similar to mofo, pronounced [moh-foh] and which dates back to the 1960s.

The expression mufo became more prevalent in 2016 on Twitter, perhaps in part to debates about the US presidential election that year that caused many people to unfollow social media friends.

"mufo" sounds like an insult, but then again it could be a subtle, passive-aggressive way to call out contacts who are doing something that annoys you.

Who uses mufo?

The notion of mutual followers, AKA mufos, is found on social media, especially Twitter and Instagram. People have a lot of love for their mufos, and it can be considered rude to unfollow or mute them.

It is less common to see mufo as motherfucker with the new spread of mutual followers, but it still sees use.

MUFON, sometimes written MUFO, is the acronym for the Mutual UFO Network, a nonprofit organization dedicated to the search for intelligent extraterrestrial life.

Mufo is not to be confused with muufo, a traditional Somali flat bread.
