Your own personal gaming terms...

[Abraxas]

Goods to Move: Anytime a player decides to scavenge everything off fallen opponents and tries to sell it in town . . .

A Zodrin Maneuver: A plan that goes horribly wrong.

I was trying to heal him: When a character gets caught trying to off an NPC without the other PCs knowing about it.

 

[Barrier Peaks]

PC Glow: The inevitable vibe a party gets from a newly-introduced PC, which facilitates his joining them on their latest quest with a minimum of fuss.

This one came up a long time back, after a PC had died and his player had rolled up a new character. Things were getting out of hand, time-wise, and the party was overly suspicious about just about everyone they'd meet. When the new PC was introduced, there was the inevitable "20 questions" and quasi-interrogation. I just wanted to get him integrated so that we could get on with our lives, so I asked the GM: "Does he have that 'PC glow'?"

The term stuck, and we continue to use it to this day.

Blit: To be killed instantly, esp. in a messy way, as if the thumb of God Himself descended from the heavens and squashed your character.

This is from my wife's previous gaming experience, long before I met her, but through her it has become a part of my own gaming vocabulary. I guess "blit" is the sound that you make as you are crushed by God's digit.

Zot: Shothand for saying, "I cast magic missle." So named after our made-up sound for a magic misle.

Hey, cool! So, I'm not the only one that does that!

Back in 2E, when backstabbing multplied weapon damage instead of adding d6s to it, my group decided that the official sound effect for a full damage backstab was "GUTCH"!

 

[Mark Hope]

Just remembered another one that my old group used to use:

Fix
To repeatedly cast healing magic on all members of the party until everyone is back at max hit points (or as near as is possible). Used in answer to the DM asking "How many cure spells do you cast, and on who?" The PCs answer: "We fix". This comes from the old D&D computer games (Curse of the Azure Bonds, etc) where it was a time-saving option that you could select when camping.

 

[Nyaricus]

Pull a Frevin - to throw a pen, dice etc at the DM or another player or to be really annoying in general. Frevin was a player who hit me IN THE EYE with a highlighter. Jerk...

Pull a Tyler - to end the campaign by an out of character betrayl of anotehr grou memeber via baclstab and then kill off the rest one by one. Tyler was a player who did this in my gamjes. Twice. Another Jerk.

 

[Baron Opal]

Dingus - generic term for a magic item, usually of unknown powers.

Mega-dingus, or sometimes Uber-dingus - A powerful magic item. You might not know what it does, but it is fancier, or glows or whatever more than your casual dingus.

Do-deca-dingus - A really rockin' magic item that, even if you don't know what it does, it just looks so damn cool you must have it.

Dingii - Plural of dingus.

 

[Fishbone]

Pants: Taken from Magic the Gathering, a long lasting defensive spell like Stoneskin or Protection From X, or Globe of Invulnerabilty, Mace of Odo, etc. Buffing is used for offensive minded spells like Righteous Might, Spikes, Bull's Strength.
lay the smack down: A very impressive display of melee might, basically if 3 or more attacks hit for significant damage or the meleer forces a death by massive damage check he has "layed the smack down"

 

[Sound of Azure]

Here's a few:

Xerox it: Phenomena of a new PC having exactly the same class, race and statistics as the previous one. Occasionally called Canon, or Lexmark. All three have been actual character names at one point.

As stealthy as a Hollywood ninja: when the fighter or cleric tries to move silently.

Ixshlay: A creature with lots of templates. Named after an infamous ubertemplated PC cleric character in our group.

 

[Aaron L]

5 foot step to Jesus = dieing.

Someone just said it one night while we were playing and it stuck.

 

[The_Gneech]

Many of these are repeats, but in our group...

Greyhawk the room
Search every nook and cranny, tear apart the picture frames, rip open curtain linings, for that ridiculously valuable treasure that's in a completely unlikely hiding place.

Greyhawk the (monster)
C'mon, you know it has gems in its stomach.

He gets a (spell) up the nose!
Used by a player who has totally had it with some villain and is taking glee in blasting him. For some reason, damage spells always go up the nose in our group.

Look! Air!
To roll badly on a Search or Spot check.

I save versus stupid.
To choose not to pursue some unwise course of action. ("Do we go into the dragon's lair?" "No, I saved versus stupid.")

Gazebo! Run!
Used when we encounter some really oddball monster we've never seen before.

Hassan CHOP!
When a sword- or axe-wielding character does a very large amount of damage.

Tent Peg
What you get turned into when the giant or other massive, club-wielding creature smacks a good hit on you.

Ker-Smite!
When a "holy" character (paladin, good cleric) lays a particularly good smackdown on undead or infernal/abyssal foes.

Whiff.
To miss with a melee attack.

You viciously shoot a rock (tree, wall, the floor).
To miss with a ranged attack.
