UPG: Unverified Personal Gnosis. Often used in neo-pagan religious discussions to preface or qualify a particular statement on metaphysical reality, this signifies that the information in question is based only on a personal revelation and not on broadly-accepted historical fact or verified documentation. If enough people share the same personal revelation, UPG may evolve over time into VPG (Verified Personal Gnosis), also sometimes known as Community Gnosis.

Anatidaephobia is defined as a pervasive, irrational fear that one is being watched by a duck. The anatidaephobic individual fears that no matter where they are or what they are doing, a duck watches.

Anatidaephobia is derived from the Greek word "anatidae", meaning ducks, geese or swans and "phobos" meaning fear.

UPG stands for Unsolicited Penis Glance. This occurs when a man is in public or a semi-public place and he witnesses or is informed of someone who has glanced in his general crotch or groin area.
