OTAH

Stands for "Oh, That's a HOOT!" Originally created as a joke by two loving grown-up children on their mother that didn't understand internet / text acronyms (To be used in place of or in conjunction with LOL, ROFL, etc.) it was later submitted to and aired on the Jimmy Fallon Show, and used extensively during the segment in which it aired.

Text acronym for the "Oh That's A Hoot"

A woman named Stacy came up with it. It's now a thing.

Acronym of "Oh That's a Hoot!"

Only use if you are trying to make a person laugh(TELL THEM THE MEANING AFTER THAT)

Only teach this to people who are actually not that smart but think that they are very smart

I saw this from the Tonight Show Starring Jimmy Fallon.
