Demographically Inappropriate Humour / The Loud House

• Clyde's frequent nosebleeds whenever he's around Lori. If uncensored bleeding on a kids' show wasn't enough, it's not every day you see an anime trope used to denote sexual arousal in a Western animated series — let alone one targeted at kids. This was dropped in the third season, due to Nickelodeon realizing the origin of the gag and the producers deciding it was reminiscent of fired creator Chris Savino's firing for sexual harassment.
• "Get the Message": As Lincoln gives a vicious tirade about Lori through voicemail, some of his dialogue is drowned out by guitar riffs and harp strings, heavily implying that Lincoln used some profanity. The same thing happens at the end of the episode when Lori sees Lincoln's "Why ____ is the worst sister ever" letter.
• "Making the Case": Lynn's section of the trophy case contains a certificate reading "KICKS A+."
• "A Tale of Two Tables" When Clyde is preparing Lincoln for dinner at the grown-up table, he honks an air horn whenever Lincoln does something wrong. When Lincoln takes cardboard Lori's bread, Clyde says, "Don't worry beautiful, I'll share my buns with you" before Lincoln honks the air horn.
• "Space Invader": After Lynn throws Lincoln's stuffed rabbit doll, he catches it and starts baby-talking to it, after which Lynn comments: "Y'know, I'm noticing a complete lack of balls in this room". Lincoln gets an uncomfortable look at that remark, which is followed by Lynn bringing in a pillowcase full of sports balls. This scene was edited in the UK and the Latin American dub softened the dialogue to specifically say "sports balls".
• "Ties That Bind": Early in the episode, Lori finds out Leni is using one of her shirts and angrily demands her to take it off. Leni responds she can't as there are boys present. The only "boy" present is Luan's dummy, Mr. Coconuts, which does an Eyebrow Waggle causing Luan to cover its eyes.
• "Along Came a Sister": There are two occasions where Lori calls the person looking under the door (to look for the tarantula) a "weirdo" for seemingly trying to peek on her when she's in the bathroom. The first time is her brother, the second time is an adult exterminator, which causes him to stutter and blush.
• "Two Boys and a Baby": A rather subtle Visual Pun where Lincoln uses a fishing rod to get rid of Lily's dirty diaper. As he reels it in, it accidentally hits the ceiling fan, a pun on the profane phrase, "shit hits the fan", spilling contents all over the room. Thankfully, it's not shown to the viewers.
• "Study Muffin": Lisa taking Hugh for a "class" in which she points out his six pack and then is about to do the same with his "gluteus maximus" while all the other sisters (sans Lily) squee in delight. It's implied that Lori snaps a photo of Hugh's butt as Lincoln escorts him out of the room.
• "Suite and Sour": The end of the episode reveals that the Louds were really kicked out of the hotel because Mr. and Mrs. Loud were caught on camera Skinny Dipping in the pool after closing time. At the end when Mr. Loud states that they will tell the kids the truth when they're older, it also implies they did a lot more than just swim naked (even though their six eldest children likely know about sex).
• "Lock 'n' Loud": Lisa accidentally reveals that she had cameras in the bathroom for a year, followed by her smiling deviously and walking back into the bathroom. Also, halfway through "House of Lies", Lisa installs cameras all around the house to detect lies from the family, including the bathroom.
• "Frog Wild": Mrs. Johnson's class is looking at Lana's new frog sanctuary towards the end of the episode when one of them asks about what two certain frogs are doing. This causes Mrs. Johnson to immediately cover the tank with a world map, implying the frogs were mating.
• "Cheater by the Dozen":
  • For most of the episode, Lincoln and Clyde assume that Bobby is cheating on Lori with no given context. Among their suspects for cheating are an older woman, a man, and even a dog.
  • They inadvertently see Bobby taking off his pants from a camera they hooked onto a collar from the aforementioned dog, causing Clyde to cover his eyes in horror, mentioning that he isn't allowed to watch R-rated movies.
• "The Loudest Mission: Relative Chaos": When Ronnie Anne lifts the shower curtain, she sees Sergio, exclaiming the words "I'm naked!".
• "Health Kicked":
  • Mrs. Loud does a seductive purr and winks to Mr. Loud after mentioning the tankini she bought on their honeymoon, complete with a saxophone sound and Mr. Loud saying, "Va-va-voom!". The kids, who are eavesdropping, react in disgust.
  • In another scene, Mr. Loud's pants fall off and Lori and Leni, who are hiding under their parents' bed, cover their eyes in disgust. This implies that he'd been Going Commando and they got an eyeful.
• "Tricked!": They probably got away with it because they reminded the audience that it was fake at every chance they got. However, the episode shows rather gory imagery such as a decapitated (papier mache) head, a lot of realistic fake blood, people being threatened by a (fake) chainsaw, a woman cosplaying as a corpse with her clothes covered in said realistic fake blood, and a child acting as a victim of a hanging.
• "Tripped!": When the Louds are on a prison bus by mistake, Lana talks to a prisoner in the back. Upon noticing one of his (offscreen) tattoos, she believes that his tattoo artist forgot the lady's clothes and proceeds to draw over the private areas with a marker.
