The underbite comments
With them being influencers with a large fanbase, I don't think it was very respectful or mature for them (especially nick) to essentially "mock" a underbite face, as its a legitimate disability that many people live with.
I might be overthinking, but I found Nick's comments to Chris during their underbite discussion a bit insensitive. What was Nick implying when he said to Chris "you give underbite vibes" or "because of the way you act, I wouldn't be surprised if you had a underbite"?? Nick has said Chris acts "autistic" and is "on the spectrum" so these previous comments about how he acts along with the mentions of the underbite are really weird things to say. There is absolutely nothing wrong with having a underbite!! Nick was just giving rlly negative vibes for no reason.
I just think that they should be more mindful about the comments they make, especially about appearances, since they don't really know who is watching.
