Lost Pause/YMMV

Growing the Beard: Noble started getting the hang of his trademark performance with the Hatsune Miku Waifu Game playthrough.
Moe: Discussed by Noble whenever he sees an example (a cute girl getting clumsy) in games.
Narm Charm In Sakura Santa, his reaction to "There's no doubt about it. I fell in love with Santa Claus..."
What Do You Mean It Wasn't Made on Drugs?: Noble mentions many times that he is not on drugs when making videos and has never done any in his life.
Unfortunate Implications:
- When you look at his channel in an ignorant way, it might seem disturbing to watch a guy clearly perving on 2D girls.
- In Hatsune Miku Waifu Game Ep 5:

Game: Selecting a behavioral synthesis engine and setting the output-
Noble: You can change the way she behaves? You can change the way she behaves?! That sounds terrible and unethical, but at the same time... Waifu material!

He was pretty disturbed with the facets of catgirls in the society of NEKOPARA, but washed it away ("Don't think about it too much!").
In Burokku Girls, Noble was very creeped out with Dr. Candy's "flirting" towards Takeshi, a teenage student:

Noble: Oh my God, we are going to get so violated. (laughs) Please, please, someone call the police!
