It's obvious that HelloDeli is writing like that on purpose, not to impress anyone, but to add another element of humor. The way I see it, it's tongue-in-cheek, and apparently was way over your heads. He wrote it in a super-dramatic tone, with lots of adjectives and import to add to the drama of going to RiteAid and doing something slightly foolish. That in itself is fairly humorous, but by writing about it as if it were the apocalypse and with such an important tone, he made it much more amusing, at least to me. I mean, stuff like "the elusive toothbrush" and "mystifying azure blue abyss" just makes the whole spectacle seem so much more humorous, because it's different and silly when compared to the subject matter. Two thumbs up, I say!
