* AcceptableTargets:
** The fanbase sees Music/JustinBieber like this. If a "kill the ragdolls" level has Irresponsible Dad's son hanging around as a target, expect him to be labeled "JB".
** "JB" is also often used as a synonym for a bad player. Often there would be levels where the map maker writes sarcastic comments if someone dies in an early spot or an easily-avoidable hazard. Example: "Even Justin Bieber could make that jump." or "If you lose, you're a Justin Bieber."
* AlternateCharacterInterpretation: Some of the more creative user-made levels, including one where the Wheelchair guy is just one of several clones, and one where the Irresponsible Dad is smaller than a mouse.
** Quite a lot of user-made levels depict Wheelchair Guy as a pedophile.
* BrokenBase: The creator's attitude towards Let's Plays in general has split the base. Some think that this is a case of him being too defensive, others think that he's entitled to his opinion and is at least content to leave them up, unlike other developers.
* CrossesTheLineTwice: You'd think general dismemberment of handicapped elders, children (and one toddler), and even Santa Claus would be nothing but horribly outrageous, but this game manages to go so far with it that it becomes ''hilarious''.
* DemonicSpiders: Any hazard could be made deadly with clever placement, but special mention goes to the Harpoon Gun. It has perfect accuracy, [[LightningBruiser lightning speed]], piercing ability, and is heavy. This combination means you'll be lucky if it doesn't make you literally explode on impact. Even if you survive, an anchored one in your body means you might as well restart; it's near impossible to get free. It's no wonder that most obstacle course levels have the harpoons nerfed.
** Chompers, which are blade weapons connected to a pin joint. If they end up in your character's body, it's only a matter of time before they tear them apart.
* FanNickname: Thanks to LetsPlay/JackSepticEye's Let's Plays of this game, the Segway Guy has been affectionately dubbed "Segway Steve". (Or "Spikefall Steve", thanks to the character's tendency to be used for spike-fall levels.) The Irresponsible Dad's son is also typically called "Billy" (and the dad "Bobby") by the playerbase, also thanks to him. Timmy is another popular name for the son, as well. (For that you can thank Jack's fellow ''Happy Wheels'' player LetsPlay/{{Markiplier}}.)
* GameBreaker: Though it takes practice, it is possible to fly using the Wheelchair Guy's rocket. Needless to say, this makes clearing most levels very easy.
** The Irresponsible Dad can do it too, to some extent. Mashing the lean keys will have him glide for as long as you can keep it up.
** Beating the "It Keeps Happening" level is ridiculously easy if you're playing as Pogostick Man. [[spoiler: Just jump upwards and the finish line is right there.]]
** Helicopter Man can straight up fly, and therefore has maneuverability incomparable to other characters.
* EnsembleDarkhorse: Irresponsible Dad is without a doubt the most popular of the current characters, likely due to being a favorite of many of the Let's Players who have taken a shot at the game. It doesn't hurt that he's tailor-made for VideoGameCrueltyPotential due to his son.
* GoodBadBug: Though some of said bugs fall into this category.
* HilariousInHindsight: One popular level was called "Jurassic World" before [[Film/JurassicWorld the actual film]] was announced.
* MemeticMutation: "Dammit!"
* MostAnnoyingSound: Pogostick Man's over-the-top screams of pain can be funny at first, but when he constantly makes them it's unbearable. Expect this to happen if you're going through the stage with a blade weapon stuck in his body.
* MostWonderfulSound: The victory sound. ''Dun dun NUUUUUUUH! (pssshh)''
* NightmareFuel: A rather major case of YMMV, as to some people all of the death and dismemberment in the game can come off as more disturbing than funny.
** Some of the user-made levels can also contain plenty of nightmarish content, such as the ones made by user "kirbypwnage" (especially his "Haunted Mansion" levels).
* ThatOneLevel: "99% Impossible" levels, which at least 90 percent of the time are fully dependent on [[LuckBasedMission luck]] in order to complete them and have the difficult-to-use Pogostick Guy as the playable character. The ones that are actually well-made aren't usually any less difficult, but at least that's because they are difficult for more legitimate reasons.
* TheScrappy:
** The Explorer Guy is one of the least popular characters in the game. Very few fans like him because he's difficult to control, very top-heavy and prone to falling over, can't jump, and a relatively useless special ability (see ThisLooksLikeAJobForAquaman). It's very rare seeing players pick this guy or there being maps where he's the set character.
** "[[BribingYourWayToVictory R8 5 To Unlock]]" levels, where an object that would make an otherwise nearly impossible level easier to complete or even the ''victory line'' is blocked to the player with a message telling them to rate the level with five stars and then it will be unblocked. Even among the more hated level gimmicks in the game, this one really takes the cake for the userbase as the uploader is attempting to artificially inflate their level's rating just so it will get a higher rating, and thus appear early on in the level lists. Combined this with the fact that the uploader rarely follows through with unblocking the objects/finish line, (likely out of fear of ceasing to get the 5-star ratings they aren't legitimately earning in the first place) and you get one of the most hated gimmicks in the game's history.
** "Naked Character Glitch" levels. All of these levels are largely identical: Your character sits inside a box with either [[{{Fanservice}} the Irresponsible Mom or the Motorcycle Couple Woman]] outside with a message claiming either that a glitch causes them to appear to be naked or that the level maker will make them appear to be so if the player rates 5. Not only does this "glitch" not actually exist (nor do the characters actually become naked unless the level maker puts a flesh-colored graphical effect over them), but once less-skilled level makers realized that they could score 5-star ratings this way (in a similar vein to the above), the level list became ''flooded'' with this type of level. Very quickly, these levels became another widely detested level gimmick and is almost always listed in lists of level gimmicks that need to stop.
