"Randy Jackson went on a tear[/color] on Twitter Wednesday night"
"tear" is not being used properly, it is a grammatical error.
If they mean he was ranting on twitter, the word would be "tearing"
Tear
a : to move or act with violence, haste, or force <went tearing down the street>
So what else does "tear" mean.
Tear
1: a : to separate parts of or pull apart by force : rend
b : to wound by or as if by pulling apart by force : lacerate <tear the skin>
2: to divide or disrupt by the pull of contrary forces <a mind torn with doubts>
3: a : to remove by force : wrench —often used with off <tear a cover off a box>
b : to remove as if by wrenching <tear your thoughts away from the scene>
4: to make (a hole or opening) by or as if by pulling apart by force <tear a hole in the wall>

So the major idea when "tear" is used as verb means, to rip apart, divide, separate...
It brings to mind the whole controversy in regards to the new album and how the fan base is divided.
Is this indicating Randy's role?
Is this controversy to test the unity of the fans, will they be there to support Michael when he decides to return, no matter the influences?
The urban dictionary definitions don't seem to fit either:
On a tear
1. On a streak or series, usually a winning streak. Will sometimes be used (semi-sarcastically) to define a losing streak. When used for a positive streak, it's similar to "tear it up."
2. A string of behaviour that is compulsive and deviant. The behaviour is typically of an "adult" nature such as drinking, screwing, swearing.
3. To have recently engaged in many sexual acts, with many different people.
