Blam
The BLAM Technique is what /tg/ calls the ability of an Imperial Guard Commissar to execute anyone he (or she, I guess) finds guilty of cowardice, treachery or 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.
Example:
PAULDRONS ARE GAY *BLAM* Heresy!
