A fictional idea, that a guy can spray himself with some crappy scent and suddenly women are drawn to him like Oprah to fries. The term is synonymous with complete crap.

The effects that Robin has on all men and women. Super magnetic personality. Man and women are falling all over her. She has them wrapped around her little finger to do her will.

The single-handed influence Judd Apatow movies have had on getting more naked penis shots into mainstream comedies. Mostly to the detriment of society. See Walk Hard, Forgetting Sarah Marshall, etc.
Dude, I just saw Jay's schlong in that Zack and Miri movie. I didn't know Silent Bob had gotten zapped by the Apatow Effect, too.

The change in the social and religious climate of a fraternity based on the addition of one brother.
4 years ago we were a house full of steaks, but now because of the Gutman-effect we have kids like Phillipe.

When large groups of people are exposed to the same exact body of facts but “intuitively” feel strongly one way or the other – polarized - based on deeper life-long accruing concerns and prejudices that have significant unconscious bearing on their decision making system (possibly selectively listening/reasoning), but generally unbeknownst to them until it is brought to light by some polarizing event that entirely reasonable people can’t otherwise see eye-to-eye on.
Jesus – I was utterly shocked OJ was deemed innocent by the jury, but every black person I know and love – to a person – felt exactly the opposite of my skinny white ass. Both sides bold-faced convicted to their vision of the obvious truth. Something larger must be going on. 'One million people' (x2) can’t be wrong. The “OJ Effect”.
As an American I went to the Japanese War Memorial Museum where me, an Aussie, and a Brit (who never met before) were utterly dumbfounded by the official Japanese vision of the events of WWII, most notably who started the war between Japan and the USA. Only then did I realize my own John Wayne exposure to the war was equally disturbing.

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.

When you recently learn about a new person, place, or topic (often from game shows, similar to Jeopardy) and then the person, place, or topic randomly comes up in conversations or reoccurs in your everyday life multiple times.
The answer to a question on Jeopardy was Keith Ferrazzi (an author), and then one of my co-workers sent me an e-mail about him inquiring if I was familiar with him. A few days later, I read a newsletter and Keith Ferrazzi was mentioned in it. This is an example of the Jeopardy Effect.
