Funny / No Matter How I Look at It, It's You Guys' Fault I'm Not Popular!
Upon working up the courage to face the cockroach everyone else is afraid of, Tomoko squishes it without remorse. And happily goes to clean her shoe as she imagines what her classmates think of her. Good news, they're not ignoring her anymore. Bad news, they now think of her as the weird quiet girl who crushes anything that annoys her, even something that has the rest of the class up and running in the opposite direction. It is both sad, and completely hilarious.
In the spinoff "It's not my fault my friend is not popular", during one of their earlier meetings Yuu hears Tomoko talking about "getting hard" and is confused by what it could mean. She then reads it up in a book and is confused by the word for the male genital, which she then looks up too and gets more confused. The whole scene makes it look like Yuu is very naive and has no clue about sex. Until the end where it's revealed she knew what it was the whole time but merely knew the vulgar term for it.
Later in the same chapter, Tomoko Googling for NSFW images on her phone in class... and getting caught when she fumbles her phone.
"My mind is so stuck on dicks I can't concentrate at all..."
Of the fraction of girls who have seen a naked guy (penis), Kuroki-san is now well-known to be one of them.
The anime OP. Nothing within the OP itself, but just the fact that a Slice of LifeCringe Comedy gets such a hardcore, heavy metal OP.
The 3rd ED. The lyrics mockingly talk about her "pure heart" and then she goes and pulls an ahegao while throwing up V-signs at 0:45.
The full version of the song makes it abundantly clear that it's about the Walk of Shame. More specifically, the Walk of Shame after doing business with a hooker.
Another moment where she ends up with an ahegao face. During an episode where she reads that sleeping while lying on your stomach can lead to erotic dreams, she tries to do this for several nights but only gets hilarious nightmares instead, leaving her extremely tired in class. Where she, during a test, accidentally falls asleep and has an erotic dream ending the episode/chapter with this face.
Tomoko tends to overreact to small inconveniences with extraordinarily venomous inner monologues which, if said out loud today, would get her suspended.
Tomoko: (Inner Monologue, regarding Yuu's physical attractiveness) If I were her boyfriend... (out-loud) I'd totally have a boner all the time!
The author's message for the English-language release of the first volume:
The many comments and d*ck pics we got following the publication of volume 1 in Japan live on in our hearts to this very day!
By the end of Tomoko's second year of high school, Tanigawa proves she still remembers the incident by making it the basis of one of Tomoko's hypothetical excuses... for looking up dicks in the early comics.
Tomoko has more money than usual from New Year's, so she does what she's always wanted to do: bitch-slap her brother with a stack of money.
"The hell did this slut just say?!?"
On Christmas Eve, Tomoko acts out with her plushie (which looks like Domo-kun) what she thinks Yuu is doing with her boyfriend: having sexwith the plushie as Yuu.
Kii-chan's expressions of anger are terrifyingly funny.
The ending of chapter 61, where Tomoko's attempt to act as the older cousin and give Kii a serious lecture gets undermined by her Implausible Deniability about the fact that she peed herself when Kii pulled a scary prank on her.
In chapter 74 Tomoko wishes at a shrine that all the girls she sees having a good time end up married to Fat NEETs.
In the spinoff: Tomoko gets a caterpillar on her head. Yuu tries to swipe it off with a broom but she swings too hard and squishes it. Instead of screaming, Tomoko spaces out and imagines she's a samurai, sword in hand.
In chapter 80, we get an extended look at how others see Tomoko. It's as painfully hilarious as you would expect. It ends with her roommate having PTSD-esque flashbacks of Tomoko.
The complete train wreck at chapter 91. The sheer amount of embarrassment and the number of times Kotomi and Akari would have to Open Mouth, Insert Foot in front of their crush, Tomoki, while Tomoko just smiles and makes it worse can't be sufficiently described in words.
Poor Akari in chapter 95. First she runs into Tomoko who casually tells her friend Sayaka that Akari wants to see Tomoki's dick. Cue Sayaka claiming that there's nothing wrong with that and her ensuing argument with Tomoko that Akari's feelings are pure much to the poor girl's increasing horror. Once Tomoko leaves she immediately runs into Tomoki and all she can do is mutter an embarrassed greeting before freaking out.
Sayaka: Akari's been in love with Tomoki-kun since middle school! She's just a pure-hearted girl who wants to see Tomoki-kun's dick!
Akari: PLEASE JUST STOP!
Savage Yuu in the christmas special of 2016.
In chapter 114 Ucchi enjoys the chocolates that Tomoko left in her locker until she notices that they fit together, and ultimately realizes that they are actually pieces of poop-shaped chocolates (that Tomoko originally made for Tomoki). Ucchi is grossed out that Tomoko would give her something like this... and eats the chocolates anyway.
Chapter 118 has Okada rescue Tomoko from Yoshida's bullying. All is well and good, until Tomoko tells her the reason she was in that confrontation (she made fun of Yoshida's panties and unwittingly mocked her), leading Okada to drag her back.
Tomoko's photos from her fishing trip with her dad. She sends a perfectly normal one to Yuu, which even makes her look cute. To her school friends however, she sends a photo of her with a half rotten fish carcass, and she's beaming with pride.
Chapter 122. So far, everything seems to be going well for everyone reading the class assignments. Until Ucchi reads hers. Even though she and the rest of her clique have been assigned to the same class and she should be happy, she's not. She's so unhappy, in fact, that she drops to ground and starts wailing uncontrollably like an infant to the panicked confusion of her friends, who can only desperately beg her to stop because she's flashing her panties at everyone. And the cherry on top is that Tomoko can only roll her eyes when she overhears this, oblivious to the fact that Ucchi's Freak Out! is entirely because of her.
In that same chapter, Tomoko's about to introduce herself to the class, and this time, she's determined to not make a fool of herself like she did in her first and second years. However, spurned on by Hina's bored reaction to her refusal to do something funny, Tomoko decides to throw caution to the wind and drops a bomb on the class that leaves everyone absolutely stunned.
"I'm currently accepting boyfriend applications! F-feel free to drop by my desk anytime."
Chapter 123. For a chapter focused mostly on Tomoki's observations on his sister's friends, we get this gem, as a response from hearing that Komiyama wet herself (and tried to pass it off as her period starting) after Tomoki spoke to her.
Itou: I thought by now that nothing Koto did could gross me out anymore. But I was WRONG.
Chapter 125, the long-awaited Disneyland Trip. And the first person Tomoko's clique runs into is... Ucchi. Who then proceeds to try and insert herself into Tomoko's group despite Mako's good-natured attempts to help her find her friends in her own class. This amounts in Ucchi throwing a temper tantrum in public just to stay in the group.
The physical comedy returns in Chapter 126, where during the roller coaster ride through Space Mountain, Ucchi gets a faceful of Tomoko's long hair. Instead of being horrified or annoyed at this though, she nearly passes out in bliss.
Tomoko causing Akane's Heroic B.S.O.D. in chapter 129 by explaining and showing her what an eroge is. She also claims that most voice actors end up doing at least one role in an eroge, including the entire cast of Crayon Shin-chan.
All of this results in the now horrified Akane immediately pulling Hina away to try and convince her to give up on being a voice actress, admitting that she was mad because her best friend felt the need to hide things from her, and then finally relenting and agreeing to support Hina since it's her dream. All very heartwarming until Hina's inner-monologue reveals that she finds the idea of Akane getting flustered at her voicing eroge or hentai "interesting" and that maybe in the future she'll tell Akane about this stuff first.
