butterfly effect 

The scientific theory that a single occurence, no matter how small, can change the course of the universe forever.

1. A man travelled back in time to prehistoric ages and stepped on a butterfly, and the universe was entirely different when he got back.

2. The flap of a butterfly's wings changed the air around it so much that a tornado broke out two continents away.

Boston Butterfly 

When a man places his anus upon a frothy trollops vagina lips (preferably long meaty hangers getting blown into by a prolapsed anus). He then proceeds to blast ass into her baby tube. The meaty lips proceed to flap like a happy butterfly nectar sucker.

I just gave Alisa the best Boston Butterfly ever! Her lips were flapping like a wounded monarch!

break a butterfly on a wheel

To use excessive force to accomplish something that can be done with far less.

Break a butterfly on a wheel: Sending a SWAT team to deal with a fifteen year old kid disturbing the peace by having his music turned up too loud.

The original phrase "Who breaks a butterfly upon a wheel?" was a line from the poem "Epistle to Dr Arbuthnot”, which referenced an ancient torture method known as the “breaking wheel” or “Catherine wheel”.
