Growing the Beard: Pre-comeback, many of his viewers felt his Fate/Zero review was when he began to grow as both a critic and a video maker. However, many of his fans feel that his comeback material starting in 2016 is some of his best material yet, mixing in both critical analysis and witty humor.
In 2019 he put out a video about "Anime Fans vs Manga Readers" that included a hypothetical conversation between the two that ended with the Manga Reader claiming "nothing you say will hurt me", only for the Anime Fan to declare "Komi-san is never getting an anime!" which enrages the Manga Reader. Two years later, Komi Can't Communicate would indeed get an anime adaptation for the Fall 2021 Season.
"If Anime Studios Were People" characterizes the personfications of Crunchyroll and Funimation as Sickeningly Sweethearts, a reference to their partnership at the time.

Though now that Gigguk has gone back to making regular videos the 2016 recap had both parts come out on time.
"Anime is trash...and so am I"ExplanationFrom his video on Eromanga Sensei, where he's come to full acceptance of the Guilty Pleasure show. This line now gets quoted whenever someone decides to admit to enjoying any "trash" series without worrying about being shamed for it.
"DOES SHOUTING REALLY LOUD SOLVE MY PROBLEMS?!"
"I will protect this smile..."ExplanationGigguk gushing about Tsumugi Inuzuka in his Summer Anime 2016 Abridged video has often been used for other moe characters.
"Sometimes, it takes a real man to become best girl." ExplanationDuring his review of spending $1000 on gacha games, he defends his decision to selectively roll for Mordred and Astolfo from Fate/Apocrypha, noting that rolling for the latter wasn't just for memes, but because Astolfo is cute.
