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.
