does IMAO mean?
IMAO is an internet acronym for in my arrogant opinionand is usually used with a sense of irony or self-deprecation.
Where does IMAO come from?

IMAO is a twist onIMHO, or in my humble opinion.One earlyIMAO comesfrom a May 1989 Usenet discussion about the jam band The Grateful Dead. The user, named David Vinayak Wallace, begins a post with: “OK then, let me cast some kerosene onto the fire. IMAO this is how I would rate” various periods of the band’s history.
Mr. Wallace then includes a postscript at the end of his post explaining thatIMAO means in my arrogant opinion to avoid “30,000 messages” asking what it stands for.
Through 1989, IMAO and in my arrogant opinionwas used 8 times in Usenet groups, always in debates and arguments. Several conversations involved complete dismissal of an opposing viewpoint, one even accusing the opponent of being homophobic. From its start, IMAOwas used with irony but also with some force. By 1993, IMAO was widespread in Usenet groups, again usually used in hot topics.

IMAO spreads online, and becomes more mild in tone, in the 1990s and 2000s, but it never quite took off like its counterpart, IMHO. That’s likely in part because in my arrogant opinion is 1) not a stock phrase in English and 2) is not something a debater usually like to admit in an argument.
Examples of IMAO

Who uses IMAO?
In contemporary online usage,IMAO is often a misspelling of another internet acronym, LMAO, laughing my ass off. That’s because lowercase L (l) is easily confused for a capital I in sans serif fonts.

When IMAO is used intentionally, it is almost always used in a self-deprecating manner, humorously undermining someone’s opinion or characterizing it as ultimately trivial. Use of IMAO can also suggest, though, that one’s opinion on the matter is more strongly held.
