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.
