rampant (adjective) 

When you describe something as rampant (RAM-punt), you mean that it is not only common, it is getting worse in an uncontrolled way. As I used it today: “[Confusion about what is meant by the ‘Big Idea’] is rampant across the marketing world. Even within The Agora companies, many marketers and copywriters use ‘Big Idea’ to mean different things.”
