Twentyspeak
is a type of spoken jargon in which consists mainly of speaking out acronyms suchs as OMG, OOC, IMHO and many others as part of a regular sentence, where in some cases it is just as easy to speak the words behind the acronym. This is most commonly used by people in their Twenties (aka millennials). Although it was originally used by hackers and gamers as "leetspeak" as a computer elitists vernacular, it's transgressed into spoken language among the millennial mass.
