might be worth highlighting more what edition things are specific to - guessing TOB is tome of battle - vaguely recall a 3.5e book
Your should add a blank line between the A-entries, the B-entries, C-entries, etc. What you have is a serious wall of text. I agree with dharkus about adding a note to indicate what edition it might be from, because some of these references are now obsolete. Many entries are overly brief and would not do a good job of explaining the term to someone not already familiar with it.
My thought, as well, is that the list needs pruning. Many of the terms are edition-specific, many of them are obsolete, and many of them may be regional, but the list ends up almost like an unabridged dictionary of gaming jargon.
Much of it is also very much outside of the scope of a Cleric handbook. For example, the "Chuck E. Cheese" build is a bard build, so why does a cleric need to know about it? (and, for that matter, why would a bard need to know about it, it's so marginal?) The Dead Alewives comedy troupe is perhaps a useful source, but not itself terminology -- you might as well put "Wikipedia" on the terminology list, in case someone wants to look up what a "glaive" is.
I'd actually suggest going the opposite way -- if you want to make a useful handbook, you want to minimize the use of jargon so that the reader doesn't need to be a lexicographer to understand the advice in the handbook.

Wait I though the Tome of Battle was ABoWFM(Anime Book of Weaboo Fightin Magic)?
In the thread Forum Lingo many of Pathfinder's jargon is discussed. The thread is not focused on jargon, so not all of the content will apply, there is a lot of joking around and site specific entries as well, so you'll have to sift out the relevant information.
i noticed that it's set to suggesting by default - you could all suggest
not in use anymore - mostly the 3.5e specific ones i think - anyone who starting playing RPGs in the last 5+yrs probably never did 3.5e
from what i understand of eberron (tech everywhere all the time) it's probably closer to forgotten realms from 4e - there's tech in a couple of countries but nowhere else really - most stuff happens in the inner region (continent of Avistan) - if you can get hold of the inner sea world guide there's a lot on the region there - then there's also the tien (far east analogue that some stuff happens in and some other places where stuff hardly ever happens
I don't think you can easily get a definition of a planet that's concise - how would you define earth? Golarion is possibly as diverse
