Why is every other word "cool" all of a sudden

Hey there fellow reptillian humanoids. Why is every other person nowadays saying "cool"? "cool", "cool?", "cool"??, it literally makes no sense. Talk to any average teenager and every other word is "cool". "Yeah I like that cool, you look cool in that cool, are you cool cool?". It's creepy. Sometimes I want to want to reply with "Look I'm trying to start a cult, you will refer to me as the final boss from now on. That sounds cool?" This "cool" fad is creeping into the middle aged people too. I don't know if there is any reason behind this but it's weird.
