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) finds guilty of HERESY (and GW had to specifically say in errata that he will not execute himself). 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. Occasionally you see orks perform a BLAM with green text after words explaining why they did so, all such blams are assumed to have actually been multiple blams, in the spirit of Dakka, and on rarer occasions, Kroot will as well. T'au pages sometimes utilize it as well, but with substantially lower amounts of blam, and a case of Eldar blam exists on the 8th edition tactics page.
Example:
PAULDRONS ARE STUPID *BLAM* Heresy!
MUSTACHES ARE FOR PUSSIES *FWIP* Heresy!
DAKKA IS DUMB *BLAM* OI I DON'T KNOW WOT YA GITZ ARE ON ABOUT BUT YA HATE THE DAKKA YOU GET THE DAKKA!!!
The Kroot will clean this mess! *Snarl*
HERESY IS SHIT! *BLAM* Here- Oh shit. Probably shouldn't have shot him. *BLAM* Excecuting loyal commissars is HERESY! *BLAM* Executing even traitor Commissars is HERESY! *BLAM* What did we just say about excecuting Commissars!*BLAM* -ad infinitum
