What does the word 'Twitter' mean?

[Robert B]

Been hearing the word 'twitter' lately.

What is it/what does it mean?

[August]

Twitter is an online site that is becoming more and more popular as we speak. Check it out at:

http://twitter.com/home

You can even search for your friends by username, first and/or last name if you want to.

Well, you could be talking about the site, or you could mean the actual definition, which is:

to utter successive chirping noises
OR
to talk in a chattering fashion

But yeah, they're probably talking about the online site.

What you are hearing about is a website called Twitter where a person makes short posts of 140 characters or less. It comes from the definition of the word meaning "to talk lightly and rapidly, esp. of trivial matters; chatter".

[Charles & Willa]

To tweet like a bird, frivolous,meaningless rapid speech.
