Blam
The BLAM Technique is an onomatopoeia for a gunshot, and is what /tg/ calls the ability of an Imperial Guard Commissar to execute anyone he (or she, I guess) finds guilty of HERESY. It is most often used by editors who search Imperium-related pages for "heretical" edits, cross them out, and edit in BLAM!!. It is also used as shorthand for said executions (as a verb), or for similar executions in a non-40k context. Also acceptable is FWIP, the onomatopoeia for firing an arrow for settings without guns, or where they are a rarity.
Example:
PAULDRONS ARE GAY *BLAM* Heresy!
MUSTACHES ARE GAY *FWIP* Heresy!
HERESY IS GAY! *BLAM* Here- Oh shit. Probably shouldn't have shot him.
