A supernatural creature whose existence can not be demonstrated, but for which certain facts are nevertheless asserted (if it's invisible, how do you know it's pink?).
Apparently orginating on the alt.athiest usenet group as a way to either argue the existence of God with non-athiests without getting personal, or mock them relentlessly. Sometimes shortened to IPU.

The Invisible Pink Unicorn is the goddess of a satiric parody religion aimed at theistic beliefs, which takes the form of a unicorn that is paradoxically both invisible and pink... imagine that.
The Invisible Pink Unicorn is commonly used to highlight the perceived fallacious or arbitrary nature of supernatural beliefs by, for example, replacing the word "god" in any theistic statement with "Invisible Pink Unicorn".
