I think I might actually start saying lol in real life and overpronouncing it so it's almost like 'lawl' just to annoy people because I'm surprised how many people are so uptight over something like an essentially meaningless phrase.
People whose main language is English, and say "lol" out loud, irk me a little bit, but I can stand it. However, a good chunk of my friends speak Spanish only, and they say "lol" out loud, and I go nuts. My cousin used to say it, and I just couldn't stand the fact that we were having a conversation in Spanish, and he would literally say "lol." It really disgusted me. How would you guys feel if I was having a conversation with you in English, and all of a sudden I started laughing in Spanish? "Jajajajaja." Makes me look stupid. Same thing applies to "lol."
Also, I just got a text from my friend right now asking me if I wanted to go out tonight. She literally wrote "What you think?". I can't stand that shit. I'm sorry, but I can't manage myself when people say "What you mean?" or "What you saying." I don't care if they say it, but for fuck's sake, don't WRITE it. It's stupid. Apparently auxiliary verbs are useless nowadays.
This one doesn't really annoy me, but I just don't understand why people say it. Why do some people (specially British people) add an "r" at the end of some words? For example: "What do you think of my idear?".
