There is no necessity to describe what a rumor actually is. Everyone knows that a rumor is something which starts from a base in the end has no fact in it.
The rumor mill is when one rumor passes on so rapidly that it spreads like fire in a forest making everyone believe that it may perhaps be a fact. Easy A Movie 2010 – Worth Watching Over And Again !!! is a perfect example of how a rumor mill works.
The rumor mill, unfortunately is much faster in between girls as compared to the guys who are not much interested in who, where, what & how. But let's see how a rumor mill works.
"Amy & Brian cross paths on street and go about their way."
A –> B = I saw Amy & Brian on Harbor street.
B –> C = Amy & Brian were together at Harbor street.
C –> D = Do you know Amy & Brian could be dating.
D –> E = Guess what??? Amy & Brian are dating.
E –> F = Omagosh!!! Amy & Brian are officially dating.
And who knows within a few more rumors Amy & Brian would have even got married and have kids? Haha 
The rumor, well, it's not a rumor really. You may have heard that famous saying, "The smoke comes from where the fire is."
So the rumor does start with a fact. But as the rumor passes from one person to another, it gets modified to meet the demands of the person spreading the rumor and the percentage of fact declines with every spread rumor.
In the end, the rumor is just a rumor with no or less facts in it.
Just like Beyonce's pregnancy rumor speculating around that it may have been fake and Beyonce Tries To Clear Crazy "Fake Pregnancy Rumors" after the rumor spread out far & wide.
What's the most bizarre rumor you have ever heard?
