reason I use subtitles is vocabulary. I just heard someone use the phrase "with aplomb"... Bruh I straight up thought he said "with a plum" and was extremely baffled by the context.
And another example earlier this week. I used to watch the George Lopez show all the time when I had cable. There's an episode where the father who has a very thick accent was saying something that sounded like "cocolded" which I just chalked up to being a Spanish word I didn't understand since they often code switch in that show ... Thanks to the help of subtitles when I was watching a rerun at my parents house, I realize he was talking about his wife cheating on him and he was saying "I've been cuckolded" ... That makes more sense.
