The butterfly effect is an idea that says that a small change can make much bigger changes happen; that one small incident can have a big impact in the future. The idea started from weather prediction. Now the term is used for many things; some are scientific, and some are not.
The term butterfly effect comes from an analogy where a butterfly flaps its wings in Chicago and a tornado occurs in Tokyo. Say you wear this butterfly effect hoodie to college and by some serendipitous luck you cause a tornado in someone's heart :). You know what I'm saying!
