When you see snow outside that's ominously yellow-colored. Or worse, when someone tries to feed you a "lemon" snowcone. Yeah, this is a ToiletHumor trope. Sometimes hilariously combined with a character's own moment of FridgeHorror when they realize what it actually is.

Due to this trope's inherently juvenile VulgarHumor, it is [[DiscreditedTrope unlikely to be appreciated]] by anyone older than 25. Or FrankZappa.

[[folder: Comic Books ]]

* Referenced in an issue of ''ComicBook/LegionOfSuperHeroes'': while working on the planet of Braal, where the snow has a natural rusty tint from traces of iron, Sci-Cop Vin Kolkin repeats a saying from his world - "Don't eat the yellow snow." Native Braalian Dyrk Magz replies wryly that it says a lot about Kolkin's world.

[[folder: Film ]]

* In ''Disney/Frozen'', [[CloudCuckoolander Olaf]] is wandering through the snow and thinking of colors for it.
-->'''Olaf:''' Yeeah, it really is beautiful, isn't it? But so white! How 'bout a little color? I'm thinkin' like maybe some crimson, chartreuse, how 'bout yellow? No, not yellow. Yellow in snow: bleurgh. No-go.

[[folder: Live Action TV ]]

* On ''Series/BuffyTheVampireSlayer'', Spike [[ConversationalTroping makes an extremely clear reference to this trope]] when he boasts about being [[CardCarryingVillain "as impure as the driven yellow snow]].
* ''ChristmasOnVesterbro'' has it in the theme song. "Alt kan ske når det er jul/ selvom vores sne er gul" (translated: Everything can happen when it's christmas/ even though our snow is yellow)
* The Winter Olympics special on ''TopGear'' had two challenges between James and Jeremy; the loser of each would have to partake of the yellow snow. Each lost a challenge, so each got to "enjoy" their prize.

[[/folder]]

[[folder: Music ]]

* Music/FrankZappa's "Don't Eat the Yellow Snow" tells the story of an Inuit boy named Nanook, his favorite baby seal and a fur trapper. And, of course, the yellow snow.

[[/folder]]

[[folder: Video Games ]]

* In the second ''Franchise/AceAttorney'' game, ''VisualNovel/PhoenixWrightAceAttorneyJusticeForAll'', Maya wants a snow cone from the closed circus concession stand. Phoenix points to all the snow all around them (since it's late December). When Maya points out that there's no syrup, Phoenix hopes to himself that she doesn't notice the discolored snow in the corner. "That's not syrup!"
* The USA commercial for ''VideoGame/Rayman3HoodlumHavoc'' uses this trope. It begins with two snowboarders who appear to be urinating in the snow, writing their names, and then we hear a wave-like sound in the distance [[ReactionShot as the camera focuses on the snowboarders staring in awe]]. The camera then turns to a bank of snow with the Rayman 3 logo written in urine, and Rayman looking at the camera, smiling. Then the commercial ends revealing that the snowboarders were actually squirting yellow liquids out of canteens.

[[folder: Webcomics ]]

* In ''Webcomic/ChannelAte'', one character offers another lemonade with a wink. The second character promptly refuses to drink it.
* In ''Webcomic/LeastICouldDo'', young Rayne says that his dad makes him eat the yellow snow when he's bad. There's a bottle of lemonade or some other yellow food just out of sight of passersby.

[[folder: Western Animation ]]

* In ''WesternAnimation/FamilyGuy'', Peter's friends give him a "lemon snowcone".
* Yeti's mysterious "lemon" snowcones in ''WesternAnimation/MonstersInc'', which he offers to visitors. The frigid remoteness of the Yeti's home and the Yeti's chronic isolation are...[[FridgeHorror not reassuring]].
* In an episode of ''WesternAnimation/SpongeBobSquarePants'', Patrick ate yellow sand.
* In ''WesternAnimation/TheVentureBrothers'', Dr. Venture is left stranded and naked in the high Arctic by his paranoid PoisonousFriend Richard Impossible. As he's wandering through the frozen plain, he abruptly steps into polar bear urine, and angrily laments how he has the bad luck to step into the only patch of Yellow Snow for miles around.
* ''WesternAnimation/SouthPark'' the game on the Nintendo 64 had snowballs as the default attack. A special use for them is to take a whizz on them (with pants unzipping sound) then let fly. Hit one of the four kids with this and enjoy the creative ClusterFBomb retaliation.
* As said by Koda from ''Disney/BrotherBear'', "If the snow's white, then it's all right. Yellow or green, it's just not clean."
* In the ''WesternAnimation/IceAge'' Christmas special, Sid sees yellow snow and wants to taste it. But Prancer, knowing what it is, quickly says "Don't. Just...don't."
