This term other than being the
abbreviation of “In My Arrogant Opinion” (Collins
dictionary), in the province of Northern Italy, Verbanio-Cusio-Ossola is also used as a synonym of “Lmao”. It became used as a joke, after it was miswritten by a teen, who asked
the definition of “Lmao”: by texting the letter “L” and “I” in lower case that seemed similar at the time.
