Occurs when a girl thinks she has found a man that will make all her dreams come true. It doesn't matter about reality--because she views him as her 'beau'--she becomes oblivious to his shortcomings and is totally enamored with the smallest of things. Even a one-word text message becomes loaded with meaning for her.
(Girl looks at her phone and smiles, all dreamy-eyed)
Roommate: what's up? You look tooooo happy...
Girl: oh nothing, I just got the sweetest text from Cedric!
Roommate: (cynically) Really! What pearl of wonderfulness did he say, if you don't mind my asking..
Girl: (with stars in her eyes) he said "Sup!"
Roommate: (muttering quietly) It's the friggin' placebeau effect at work again...

The Luca effect describes the process of people assimilating with the incredible Luca due to spending an immense amount of time with him. They start picking up his behaviours as for instance smoking or eating a lot of meat and also his type of humour. The effect was observed and proven many times by his closest friends.
“I heard that juli has become a chainsmoker over the last few days.”
“Haha it must be the Luca effect!”

The Mirage Effect occurs when you see a female with a Phat ass and the ass alone makes you think that the female is attractive but she is actually not.
Damon: Wow that girl has a phat ass and is hot too!
Matthew: Dude, she isn't even hot, it's just the Mirage Effect taking place.

Turns you into a flaming liberal.
Watching Fox TV with my dad for the day had the fox effect on me. I have always considered myself slightly conservative but after the fox effect took hold I am practically a commie.,
