Ninja'ed

Not to be confused with the Ninja role.

To be ninja'ed is to have someone else post while you are writing yours, thus triggering the forum's automatic warning (since phpBB3) and preventing you from posting without clicking yet another box.

Repeated ninja'ing in a very busy thread has been known to make players pray fervently for some sort of Daykill power. In extreme cases of ninja'ing, avatar fads have been known to ensue.

In addition to the "normal" ninja'ing, there is the legendary True Ninja, in which two players post at the exact same second, and so neither have the post warning triggered. One case of this has been documented so far, and it was humerous.
