Ostrabate 

The act of standing around trying to decide what to do next. While ostrabating, a lot of time is wasted. Usually occurs in a large group.

Guy 1: why can't we think of something to do?

Guy 2: I know! Why did we stand here and ostrabate for an hour?!?!

Guy 3: We have wasted the better part of an evening!

Ostracitionary 

The wiki dictionary that results when contributors are ostracized by system adminstrators.

I could not find the definition of an ostracitionary in the Wiktionary.
An ostracitionary is an incomplete dictionary.
I know its an ostracitionary because it defines the word troll but not the word ostracist.
