A cool way to say "yeah" or "yes", but is being hijacked by Olympian Ryan Lochte to mean anything.

A replacement word for Yeah or Yes.

The word "JEAH!!!" is an interjection that can often be used in the place of "Yes" by individuals who prefer to answer simple questions with extremely loud and inappropriate responses.

"JEAH!!!" can also be used in agreement of something that is not a "yes or no" question, similar to saying "that's awesome." Often this interjection can be used at random intervals when no questions are even asked or in the middle of an awkward silence.

For added emphasis, more consonants may be added to the beginning of the word. The longer the "build-up" to the "climax," the greater the effect.
Thus,
"JEAH!!!"
becomes
"FVJEAH!!!!!"
or even
"CHVSHBVWDTRVDSFKVVJEAH!!!!!!!!!!!!!!!"

It is important to not confuse "JEAH!!!" with its cousin "MYAH!" which has similar useages, but is of different origins.

Although the true history of the word "JEAH!!!" is shrowded in mystery, it appears to be either a degradation of the word "Cheah," which is believed to mean "Cheers," or it is simply a rebellious form of the word "Yeah," coming from "Yes." Scholars are still in debate to this day on the matter.

another meaing for "yeah"

Catchphrase of multiple world record holder and Olympic gold medalist in swimming, Ryan Lochte.

According to an article published on UniversalSports.com Lochte explain: "It means everything, like, happy. Like if you have a good swim, you say, 'Jeah!' It's good. So I guess it means, 'good.'"

A word often used when getting boozed, it can never be over used and should make the entire crowd laugh. Originally from Northern California but has spread across the world. Webster thinks it should replace the words "Yeah" "Yes" and "Ya" but we'll see what happens in 2012. The most recent usage of the word "jeah" has been used while "cougar hunting" in the myst of arizona. Not only do the elder folks shun it, it happens to be the most simple often used pick up line among college students. When in doubt always remember that "jeah" is the new "fuck". That is one simple thought to sleep on.

Means hell yeah
