A barrier which separates the mundane from the Transcendent Reality. A true Wonderwall will always have a crack, or a slit or an opening which allows anyone a glimpse of what lies beyond the Wonderwall.

The word wonderwall is a metaphorical term used to describe a person, place, or event.
It is also a compound word.

Wonder- To be filled with admiration, amazement, or awe.

A curiosity.

Wall- Any of various permanent upright constructions having a length much greater than the thickness and presenting a continuous surface except where pierced by doors, windows, etc.: used for shelter, protection, or privacy, or to subdivide interior space, to support floors, roofs, or the like, to retain earth, to fence in an area, etc.

So a wonderwall can be widely considered as a noun that is a strong foundation full of admiration.

In other words, it is something that gives you strength.

As it is a versatile expression, it may be used as an adj.
As cliched as this is, "you are my wonderwall."
or,
"I never realized before now, but that moment was my wonderwall."

Something (most typically a song) that has been so over used that it is boring and painful to hear. No matter how brilliant you thought it was when you first heard it after the millionth time today on the same radio show it is now annoying.

Named after the Oasis song of the same name which, despite being brilliant in many ways, has been rejected by many fans as "a bit wonderwall" due to over playing on air.
Person 1: "Have you heard that new Blur song?"

Person 2: "Only a million times already today... I did like it but now it's abit Wonderwall"
