Don't tease or mock anyone in a horror film. The monster doesn't like it, and will kill you for it. Not that the monster actually likes the people you mock (it will kill them too). It's just that mocking is the monster's thing. You're butting in.

So don't tease people, don't treat anyone like they're crazy for talking about the monster, and don't play any practical jokes. The last one isn't a DeadlyPrank, where someone will get hurt. The monster will just kill you later for pulling one.

Note that this doesn't count if the people you tease laugh with you. That isn't mocking; it's just having fun.

Compare DoNotTauntCthulhu, DeathBySex, DeathByMaterialism, DeathByGenreSavviness, DidYouJustFlipOffCthulhu, LetsMockTheMonsters (when the characters decide to go one step further).

[[folder: Film ]]

* ''Film/AnacondasTheHuntForTheBloodOrchid'':
** The characters are wading through a river. One guy keeps humming the ''Film/{{Jaws}}'' theme. A girl keeps telling him to stop (instead of just punching him in the face). He's one of the first victims.
** Subverted later when another character is taunting a freshly killed anaconda snake, only to be grabbed by another. Unlike the previous victim, the other characters manage to save him from death at the last minute.
* An aversion occurs in ''Film/{{Scream1996}}''. Two guys pretend to be the killer in school. They don't get killed for this joke, probably because the principal who punished them (and who gets killed later) was even more obnoxious.
* In a ''Film/{{Jaws}}'' knockoff ''Film/BlueDemon'', some girls are sneaking into a closed beach. The fence is electric, and two of the girls tests it. It's off, but they act as though they're getting electrocuted anyway. They eventually get eaten.
** ''Film/JurassicPark'' has a similar scene, but the victims laugh at that (well, one of them does), so the joker lives to the end (and even through [[Film/JurassicParkIII the second sequel]]).
*** ''Film/TheLostWorldJurassicPark'' had a guy who taunted a Compsognathus later get eaten by a pack of them, however.
* Averted in ''Film/FridayThe13thPart2''. Right before Jason really gets started building up his body count, half the characters go into town to go drinking and essentially leave the movie. The practical joker (Ted) goes with them, and survives to the end credits. However, the joker character does indeed go down in parts [[Film/FridayThe13th1980 I]] (Ned), [[Film/FridayThe13thPartIII III]] (Shelly), [[Film/FridayThe13thTheFinalChapter IV]] (Teddy) and [[Film/FridayThe13thPartVIITheNewBlood VII]] (Carrie-esque RichBitch Melissa).
* ''Film/{{Carrie 1976}}'' was [[BewareTheNiceOnes pushed over the edge]] by a particularly malicious prank that was the culmination of all the nasty teasing, taunting, humiliation and pranking done to her by the girls in school. She proceeds to kill just about everyone at the prom before taking her RoaringRampageOfRevenge elsewhere.
* Spoofed in ''ScaryMovie'', and later in the third film when Brenda pranks Cindy by saying she watched the killer videotape, and then pretending deaths... and as Cindy is out of the room, "Samara" comes out of the television and kills Brenda (specially because Cindy [[CryingWolf wasn't believing her cries anymore]]).
* Steve in 2004 version of ''Film/DawnOfTheDead2004''. His fault? Bickering with Anna. His punishment? Zombification then bullet through the brain. Riiight...
** You left out "nearly got the heroes killed by abandoning his post when he was supposed to open the back door and let them in."
* Averted in ''Film/{{Tremors}}'', where Melvin the prankster manages to survive to the end of the film, and even appears in one of the sequels and the TV series.
* In ''Film/FreddyVsJason,'' Kia tries to show she's not afraid of Freddy by mocking him to his face. Jason chops her in half from behind.
** A pair of ravers meeting Jason for the first time mock him. [[TooDumbToLive This does not end well.]]
* Anybody who mocks Michael Myers in the ''Film/{{Halloween 2007}}'' remake doesn't last very long.
* ''Film/NightOfTheLivingDead'': "They're coming to get you Barbara..."
* A tv-movie "The Girl Most Likely To..." had a homely, overweight smart girl subject to routine humiliation in college - after she flees one too many and gets in a car wreck, months later she emerges from reconstructive surgery slim and beautiful, and unrecognizable to her former tormentors who now regard her as one of 'them'...she kills them one by one.

[[folder: Live Action TV ]]

* ''Series/BuffyTheVampireSlayer'' lampshaded and then subverted this.
-->'''Xander''' (in a voice like talking to a baby): Who's a wittle fear demon?\\
'''Giles:''' Don't taunt it.\\
'''Xander''' (getting up, looking scared): Why? Can it hurt me?\\
'''Giles:''' No. It's just... tacky, that's all.

[[folder: Theatre ]]

* Nearly happens to Mortimer Brewster in ''Theatre/ArsenicAndOldLace'', as he's spent a good deal of the first act mocking his [[CainAndAbel older brother]] Jonathan, who of course later shows up and turns out to be an AxCrazy SerialKiller who fully intends to make Mortimer his next victim.
