A few things that caught my attention in this:

• GoodTimesWithScar’s /æ/-tensing. The phenomenon is messy, as it depends on the dialect and the phonetic environment of the vowel, but before /n/ most speakers of North American dialects would realise /æ/ like he did, [ɛə̯]. Another example of the same phenomenon would be Etho, who’s from Canada.
• GoodTimesWithScar’s regressive nasalisation. The video transcribes it accurately as ranging from the start of the diphthong, not just near the end; that hints that, at least in his dialect, vowel nasalisation is already phonologised.
• MumboJumbo’s [h]. I think that he’s being cheeky and playing with how others pronounce the word; do note however that /æ/-tensing is not common in the UK, where he’s from.
