zmanning 

-To derail a thread in a very idiotic fashion reminiscent of the totsean Zman.
-To make a completely idiotic comment that is inarguable yet blatantly wrong.

...and then he said "the Iraq war is totally justified", and I told him to stop zmanning the thread.

Zhanning 

To act within a deviant manner - to act in a casually socially unacceptable way.

People who Zhan are referred to as Zhanners.

Dude 1: "Hey, has anyone done the assignment for tomorrow?"
Dude 2: *Sends picture of naked Goku to the group chat*
Dude 3: "Nahhhh bro he's zhanning"

The Zhanning 

The 2nd of May, where all acts of Zhanning are allowed with no consequences. Like the purge, but for Zhanning.

Today is The Zhanning - All Zhanning today on the 2nd of May is legal and will have no consequences.
