These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternate Character Interpretation: Does Trina deserve the things that happen to her for her mean and horribly selfish attitude or is she just a poor girl with issues that the band cruelly exploits.
In "Math of Kon" a completely different side of Trina is shown that makes one wonder which side is the real Trina; the nice(er) mathlete or the mean Alpha Bitch.
"Dreamreaver" implies that Trina locked away the nice side of herself in her mind, and she used to be a real kind and fun person. Her full name was Katrina, but according to Corey "No one's called her that in years." This change seems to have happened after Nick Malory entered her life, making it a case of Love Makes You Evil.
Mina, why does she help Trina so much? Is it because she terrified of Trina? In Love with Trina? Is she just as mean as Trina? Does she just enjoy the side benefits of being Trina's friend and is willing to do anything to keep them? Or does she see her as the kind girl she used to be?
Corey himself. As commented by his friends, he has the passion and talent to come up with new lyrics (generally in the "pseudo-Aesop" end segments), so him blatantly parasitising his sister's diary is either the sign of extreme laziness, deliberate assholish behaviour, being oblivious, or something else.
What exactly is the deal with Nick Mallory and Trina? Some episodes show him ignoring and sometimes even loathing Trina yet other episodes he is his usual kind self to her.
Awesome Music: Grojband has one awesome song per episode. The background music when Trina goes diary is pretty awesome, bonus points for changing the tune depending on the emotion.
Nick Mallory and Pinktastic (to be fair, Trina's soul was possesing it).
Cargo Envy: An interesting subversion in "All You Need is Cake". Mina is jealous of Trina's sweater, but Trina is treating the sweater as if it were a person.
Crosses the Line Twice: The flashback showing why Trina is scared of puppets. Trina's just an innocent little girl back then, so it's sad to see her scared...and then it turns out she accidentally picked up a scary puppet that just happened to look exactly like the "pretty puppet" she wanted, and the whole thing crosses the line into hilarious dark comedy.
Fandom Rivalry: With Uncle Grandpa, as fans of Grojband in the US are prone to blame Uncle Grandpa as the reason for the lack of reruns during Cartoon Network's fall 2013 season (in Canada these same episodes came on Teletoon after their US airings). May or may not calm down once the last half of season 1 begins airing in both countries, though.
There's a sizable fan community for Nick/Mina, who ship them because Nick is one of the nicest characters in the show and Mina is a long-suffering woobie, not to mention Nick being out of Trina's reach theoretically could reset her back to her nice former self (and allow her to get with Kon). There's also a surprising number of fanart for them.
That said pretty much everyone ships Laney and Corey, pretty much the vast majority of fan art features these two.
Strangely enough, there seems to be a hefty tumblr community who ship Kon/Trina, mostly thanks to the episode where Trina was showering Kon with affection when she thought he was a dog. It seems like a Crack Pairing at first glance, but Word of Godclaimsotherwise.
Kin/Kim is also a popular ship.
G'ORB/Holo-Laney seems to be popular as well.
"Funny Aneurysm" Moment: The Song in the episode "In-D Road Rager" titled "Trash, Bash, Burn and Crash" includes the lyrics "You better move and play it safe, cause when you drive out of control you're gonna shake, flip and roll." this episode aired on June, 12th 2013, The same day. NASCAR racer Jason Leffler was killed when his car lost control and crashed during a sprint race.
Mina asking Trina if she and Corey are related in "War And Peaceville" is a little more cringe-worthy when Word of God confirms they were both adopted by a single father.
The whole episode is actually a bit sad when you realize Corey and Trina aren't blood-born Riffins. They're representing their adopted family.
Germans Love David Hasselhoff: Despite being on hiatus in the United States and Canada, this show is also being Broadcast in Australia, France, Italy, Latin America, Poland, and the UK dubbed in different languages.
Growing the Beard: The show, while enjoyable, really started showing how good it can be with the two part Dreamreaver.
It Got Better with "Six Strings of Evil", which includes a killer rock song.
The currently unaired episodes really expand on the grojband universe, how so? Well there is some continuity from previous episodes, the Newmans making bigger appearances, more experimental songs , and expanding on Laney's crush on Corey.
Another one for Bryn in the episode "Girl Fest" where Laney really delivers emotion with her rage filled Take That song, "You're So Untrue".
For the first time in the series somebody else plays the Once an Episode song in "War and Peaceville" Nick Mallory and its...just wonderful. Intrestingly enough Graeme Cornies, Nick Mallory's voice actor, is an actual singer like Corey's and was the original voice of Corey.
Even DeKar Brown, Mayor Mellow's voice actor, sings along with Grojband in the song featured in the episode "The Pirate Lounge For Me".
Jerkass Woobie: Trina may be a jerk, but some viewers feel sorry for her with the band ruining her life just so they can steal song ideas from her diary.
Somewhat averted (subverted?) in "Pox N' Roll", where the scene where she writes in her diary was inspired by happiness from kissing Nick Malory's ear. He turned at the last second, and she had her eyes closed and thought she'd kiss his lips, but she was still overjoyed. It seems the band is using her diary regardless of whether or not she's angry, its just that anger is the emotion Trina feels the most.
Then in "No Strings Attached", the band uses fear, which REALLY pushes Trina to woobieness, but its somewhat deserved.
Sadness is probably the worst, sad music and eyes filled with tears along with a really sad face and instead of writing in fire she writes in storm clouds. It's only mitigated by the fact that in the episode "All you Need is Cake" Trina is being melodramatic over a sweater, one that she gets back immediately after writing the diary entry anyway.
Ultimately, Trina does tend to bring this on herself and there have been episodes where Corey doesn't think to use her diary for lyrics until she instigates something in her vendetta against her brother's band. She's mainly a Jerkass Woobie because we see in flashbacks that she Used to Be a Sweet Kid and even see that sweet kid still alive inside her brain in one episode, so knowing that, it's more difficult to not feel sorry for her even when her suffering is self-inflicted.
Mina isn't your typical jerk, but she seems more than happy to help Trina make her brother and his bands lives miserable. Then take a look at how Trina treats her, and well... it's hard to not feel a little bad for her.
Moral Event Horizon: Some episodes show Trina to not be that bad of a villain or even a threat, in fact in some episodes, Trina is the victim or even the hero. In "Here Us Rock Part 2", however, she is at her worst. She ends up sabotaging Grojband when they were trying to save the world, She horribly tells Mina off, and instead of choosing to save her she instead wants to save Nick Mallory who isn't even in to her. (Did we mention she also kidnaps Mallory out of his free will while doing this?)
Nausea Fuel: In "Smash Up Turby" when Trina grabs Mina's tongue and uses it to clean the barf off her face.
There is ALOT of barf in "Kon-Fusion"
Never Live It Down: On the Canadian website, Larry is seen flipping a coin in the "Battle of the Bands" intro video. Since then, fans have portrayed the coin flip scene as a Character Tic, often saying it's his lucky coin.
The Scrappy: Mayor Mellow. While he's by no means a dis-likable character, he's usually ignored by the fans.
Some Anvils Need to Be Dropped: Surprisingly. In one episode the band is expected to perform at a vegan restaurant, and Laney angrily makes the distinction that being vegan simply means you don't eat or use products made from animals instead of having to act like a hippy who wears leaves for clothes and doesn't bathe.
Likewise, some first-time viewers would also assume that Larry's a girl.
The Woobie: Mina, she can make some really sad faces when Trina is being mean to her or ignoring her. Overlaps with Jerkass Woobie since Mina is actually willing (VERY willing!) to help Trina in her evil schemes rather than being forced to.
In "The Bandidate" While the town of Peaceville are protesting against Trina they also attack Mina despite her not doing anything other then being Trina's lackey. At one point Trina even tries to blame the whole thing on Mina
What Do You Mean, It Wasn't Made on Drugs?:While the premise may seem tame the presetation is EXTREMLEY out of the ordinary. There is so much weird stuff going on in Peaceville and the surrealism, while not up to regular show standards is still pretty high. You can expect every episode to have its own WTF moment and thats not even counting Trina writing in her diary...
