Often believed, by those who don't understand the term's origin, to be spelt (or spelled, for the American audience) 'sike'.

Deriving from the word psychology, psych is a term used to indicate that whatever the person speaking just said was done so purely to mess with the listener's mind, to 'psych' them out, if you will.

Lassie: We don't have balls.
Shawn: ... I honestly don't have a response to that.

Shawn: Remember, Dad. Treat a woman like a person, then a princess, then a goddess, then a person again.

Shawn: Gus, don't be an incorrigible Eskimo pie with a caramel ribbon.

The newest nad coolest show on the USA follows the life of Shawn Spencer(James Roday) and his friend Gus(Dule Hill)as they solve murder cases for the Santa Barbra Police Department. Shawn has a photographic memory to help him thanks to his father Henery Spencer(Corben Bernsen) who is an ex cop and tried to force Shawn to grow up and become a detective. Shawn is pretty lazy and too interested in having fun and dating hot chicks to go thru the long process of being a cop detective so he uses his PG memory a a fake "Psycic" pretending to get preminnisions and having the ability to communicate with the dead.
other characters incude: Carlton Lassiter(tim omendsun),Julliet O'Herra(maggie Lawson) and Keren Vick(kristen nelson)
