MUTU— ORIGIN, MEANING & USAGE

Mutu 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.

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.
