The Sean Effect 

!Where the presence of one individual will bring good fortune to others around him/her. This can be in any part of life, benefits in work in one's romantic life. However, for the person causing the effect, there are usually no benefits.

I guess it's the Sean Effect when I'm around you good things happen.

Man ever since I started hanging out with you, I somehow found a girlfriend and I'm doing great in general thanks, man! I guess the Sean Effect is real!

The Sean Effect 

The process of picking up a fantasy basketball player who has had a good game, but then produces shit stats when you play him. Once dropped from your team, the player proceeds to have good games again.

Person 1: I picked up Yogi Ferrell from waivers. He had a good game yesterday.
Person 2: But he only scored six points today.
Person 1: Yeah that's pretty shit. I'm going to drop him now.
*Next game Yogi gets 9 assists and 11 points*
Person 1: Fuck, I got hit by the sean effect! I'm going to pick up Yogi again.
