* By own admission, the author of the ''StarWars''[=/=]''MassEffect'' crossover ''FanFic/{{Fractured}}'' does this a lot. It goes UpToEleven in the sequel, ''[[FanFic/SovereignGFCOrigins Origins]]'' becoming almost [[OnceAnEpisode once-a-chapter]] for a good stretch.

* In the author's notes of Fanfic/FuckTheJesusBeam, readers are commonly referred to as "[[CountryMatters cunts]]". It later turns out that this is short for "Cool Understanding Never Terrorizing Superpeople".

'''Sonic''': No, it means you beg for mercy! ''[high-fives Link]''\\
'''Franchise/{{Kirby}}''': It also fits because Team Z.A.P. is an acronym of initials too!\\
'''[[Franchise/SuperMarioBros Bowser]]''': Yeah…That's still a pretty clever name…beats G.E.B., that's for sure.\\
'''Zelda''': Oh yeah! We are awesome baby! '''Z.A.P'''!\\
'''Amy''': Z.A.P.?\\
'''Zelda''': It's our new group! Zelda, Amy, and Peach! I tried P.A.Z. but it didn't catch on…

** The '''U'''nited '''R'''oyal '''I'''ndomitable '''N'''ational '''E'''questrian forces

* ''Fanfic/ThousandShinji'': While they're checking weapon upgrades, Shinji grows frustrated with the number of nonsensical-sounding acronyms:
-->“Well, there’s the boom pistol, or rather the '''APHEGSRB-PV''', or Pistol Variant. It was developed along with the carbine version you’re using, but as the name suggests it is smaller and has a somewhat shorter range. And then of course there is the '''RCPTCCW''',” Misato says.\\
“What is with all the acronyms?” Shinji asks in annoyance.\\
“It’s a military organization, live with it,” Misato says with a shrug.\\
Punching in a few codes in his entry plug, Shinji examines the meaning of the acronym before saying, “'''R'''otary '''C'''hain '''P'''rogressive '''T'''ooth '''C'''lose '''C'''ombat '''W'''eapon… you made a giant chainsaw!”

* BeautifulDestroyerSailorMoon gets in a couple of good ones, starting with the title itself [[note]]BDSM[[/note]]. The one that really takes the cake though is '''W'''e '''A'''re '''F'''anatical '''F'''ans '''E'''nthusiastically '''N'''eeding '''S'''ailor '''S'''enshi or W.A.F.F.E.N. S.S.. They even have armbands.
* ''Fanfic/TheNewAdventuresOfInvaderZim'':
** Episode 13 has the conspiracy group known as the '''C'''onspiracy '''R'''eaction '''E'''ngagement '''A'''nalysis '''M'''onitors. Steve is quick to lampshade it, and one of the group's agents admits they didn't look at how it was written until after they had copyrighted the name.
