What Does 'Mutu' Mean?

Brainrot Score: 4.0OBSERVED
[ FRENCH INTERNET CULTURE ][ GEN Z BRAINROT ]

Someone you mutually follow on a social network — you follow them, they follow you back — clipped from the English loanword "mutual" using French internet slang's habit of truncating words down to a short, punchy form.

REAL-WORLD EXAMPLE

"On est mutu depuis un moment mais on s'est jamais parlé."

LORE & ORIGIN

Borrowed from English "mutual" and shortened per French internet/SMS slang's standard truncation convention (the same pattern behind actu from actualité or resto from restaurant), used mainly by teenagers and young adults to flag that a follow relationship is reciprocal — a marker of at least mild digital closeness or shared interest, distinct from simply following someone who doesn't follow back. Plural form is mutus.
