[Idiom] Double psyche

[ViggoC]

What's the meaning of double psyche?
I saw this phrase when I was watching South Park.
I searched it on Google, but can't find out the meaning.
PS:I'm not a native English Speaker.

The character probably said "double psych!" Psyche is a noun, pronounced in two syllables. Psych is an exclamation meaning something like I fooled you! Doubling it presumably means Boy, did I ever fool you this time!

It would be helpful to have more context. What was the situation in which the character said this?

In my university days the phrase double-psych referred to a double period of psychology class, in the same way that double-anthro meant a double period of anthropology. I don't know if this is relevant to the example from South Park.

I am familiar with the program South Park and with this specific reference. The phrase "double psych" in this context means "I fooled you twice."
