Have you ever said a word so many times that it loses all meaning? If not, try it now. I suggest the word “waffles.” After a certain point in repetition, the word simply becomes meaningless noise. It’s a psychological phenomenon known as Semantic Satiation.
If you think they were just spitting word salad though, think again! In the settings, turn on Closed Captions and change the language from “English - Hodor & Groot” to “English - Translation Lyrics” to see all the sick burns in real time.
