People who try to sound smarter than they are and how they abuse newly found words to add to their vocabulary. "Look, I learned a new word! I don't know how to properly use it, when to use it, and whom to speak it to, so I'll just take my chances and spam this word over and over until I use it right!" When they could've just simply fucking looked at the word in the dictionary itself to better understand. That or you know, there are some conversations and situations where it's okay to use simple language. People sometimes turn a conversation when they're asked about how the weather is, into a monotonous exposition of breaking down every detail of the weather of that particular day. Dude, it's just fucking sunny, warm, and with some clouds out. Stop complicating shit!
