Caterpillar Effect 

When a person you start a relationship with morphs over time from a beautiful butterfly to a caterpillar.

Hey have you heard John started dating this hottie name Mary. Oh give it a little time, she let herself go and she won't be anything like she is now. She's the kind that will have the Caterpillar Effect, just look at her mom.

Caterpillar Effect

What the "Butterfly Effect" might have been called if previous things had gone a little differently!

You can't make blanket statements like that. Things might have ended differently due to the caterpillar effect!"

The Caterpillar Effect 

The phenomenon experienced on the road when someone decides to slow down their car to look at something of interest on the side of the road. This causes that area of the road to slow down for the following hours. This leads to cars, collectively, mimicking a caterpillar walking.
The phenomenon is easily observed on highways.

MAN! Some jerk decided to stop and look at one of the millions of car crashes a day and it's making everyone feel the Caterpillar Effect for the next hour!
