As an old person, some of my biggest pet peeves are the noises young people make when communicating. "Yolo", "swag", "swole", "fleek", etc. I understand that slang evolves over time, and is slowly incorporated into our vernacular. Each generation has their own speech patterns and idioms. I still think "rad" is the best. I'm aware that this is just me being a cranky curmudgeon.
