!!General:

* AcceptableTargets: Postal 2 lets you shoot Islamic (Hindu? [[FridgeBrilliance Maybe Pakistani?]]) terrorists, MoralGuardians, the game's developers, and shotgun-wielding rednecks, among others. The expansion also includes a PETA-like organization.
*** Postal III has all that plus violent anti-porn Hockey Moms and [[TakeThatAudience annoying video game nerds.]]
* AlternativeCharacterInterpretation: The first game suggests that the Dude is some sort of WellIntentionedExtremist; however, the presence of a moving truck outside your house in the first level has led some to conclude that he's snapped because he was foreclosed upon.
** Confirmed by Postal III's intro.
* BigLippedAlligatorMoment: The ostriches in Postal 1.
* CatharsisFactor: To varying degrees. Postal 1's atmosphere may repulse or disturb players. Otherwise, the sequels play this straight.
** Postal III features Creator/UweBoll, kill-able in the same way you could kill Gary Coleman in Postal 2.
* CrazyAwesome: The Dude himself.
* CrossesTheLineTwice: When the over-the-top gore whips back around and becomes funny again.
* CultClassic: Mainly Postal 2 as it is the most well developed compared to the first and especially the third game.
* DudeNotFunny: The rather blatant violence against certain groups (animals, random civilians, police/servicemen) smacks a little too hard if brought into the light of reality.
** The game's initial start-up screen is the developers blatantly stating that this type of violence should stay in the game and not be played out for real.
* FunnyAneurysmMoment: In Postal 2, you have the option to kill Gary Coleman (canonically, he dies whether or not you kill him), which, if you killed him, has the Postal Dude ask his wife how much an autographed book can sell for. Remember this game did star Gary himself, and was made before his death...
* GameBreaker: The likely reason that the ''Apocalypse Weekend'' expansion does not have a multiplayer component is that the new melee weapons are so much more effective than, well, every other weapon in the game.
** The 2013/2014 patches have gone some way to avoid this - whereas in earlier versions of ''A Week in Paradise'' you could get the machete five seconds into the game, now it takes significant effort to find anything of comparable power before the halfway point. And then Enhanced Mode goes straight towards this trope, with higher-powered weapons being much more plentiful, and new bonuses such as [[BottomlessMagazines no upper limit on any ammo type]].
* GoodBadBugs: There are several - lighting yourself on fire makes the instant-death fire harmless, dogs can [[LadderPhysics float up ladders]] to get to you and propel you skyhigh, and one well-aimed rocket lets you skip the "Confess your sins" and "Uncle Dave's birthday" chores.
** You can prevent the Parents for Decency from storming the RWS HQ after you collect your paycheck just by dropping a grenade in the path of the one guy who rallies them all up to go forth and kill you and the RWS guys. When the in-game cutscene plays, he sets it off and dies, and the rest just stay there. It won't prevent some scripted protesters from showing up to attack if you try to exit out the front door, but it does mean you won't get shot in the face the instant you regain control of yourself and have much fewer people to fight off.
* GuideDangIt: When you're off to get the Krotchy doll, [[BossInMookClothing Krotchy]] himself decides to fight you if you're on your way back from the back of the store. And he has a rocket launcher with him. Of course it's easy to defeat him prior to fetching the doll, and [[GoodBadBugs spamming the gas can and setting him on fire literally breaks his ability to use the rocket launcher for a while.]]
** And you can trade him a signed Gary Coleman book for a Krotchy doll to skip the entire sequence. Or just buy it off of him (any amount of cash seems to do, but he'll take all the money you're carrying).
* ScrappyLevel: The brewery in Postal 2.
** The Military Base to the end of the game are a long string of these in ''Apocalypse Weekend''.
** Meat World, specifically the final stretch where you have to fight your way back out of the building that is now swarming with cops and SWAT. After you've likely used up all the health items in the area and the SWAT are much tougher and better equipped than the butchers you just fought.
* SoBadItsGood
* {{Squick}}: Tons of it.
** In Postal 2, you can pee on things. Peeing on people generally causes them to throw up violently, with some fairly advanced liquid physics for the game's time. In one level, the Dude gets gonorrhea, and his urine becomes green and burns when you pee, which guarantees that people you pee on will throw up in reaction. And it's possible to decapitate someone as they're vomiting, causing it to continue to spew out of their neck stump.
** The cats and dogs in S&M gear near the end of Apocalypse Weekend.
