The discussion centers around the misuse of the word "literally," particularly when it is used to express hyperbole rather than its actual meaning. Participants express frustration over this trend, noting that it reflects a misunderstanding of language and logic. The conversation expands to other language pet peeves, including the use of "like" as a filler, which some argue serves to soften statements rather than detract from them. There is a debate about whether language is arbitrary or structured, with some asserting that while vocabulary can evolve, the fundamental rules of language must remain to ensure mutual understanding. The fluidity of language and its cultural reflections are acknowledged, with participants recognizing that changes in usage do not necessarily equate to degradation. Overall, the thread highlights concerns about clarity and precision in language amid evolving usage patterns.
