Glass Onion

Originating from the Beatles song "Glass Onion" off their 1968 self-titled, or "white" album, the term was believed to mean a glass-lidded coffin by the followers of the Paul is Dead conspiracy.
The real meaning of the song is that people were over-analyzing the Beatles' lyrics.
A glass onion is something that would have layer after layer peeled away, only to realise that it was transparent all along.

A pipe made of glass or lexan that is used to smoke marijuana or narcotics through, the term "Glass Dick" is too well known and the term "Glass Onion" is less known to the square non drug addict crowd and drug abusers love to use it due to a beatles song that talked about a glass onion and everyone knows about the beatles and their drug use, Glass is also a street term for crack cocaine.

Sorry, the Beatles did not invent this term. A Glass Onion is just an onion shaped bottle that was invented in the 17th century. Determine is also often used to describe glass onion like door knobs.

“ looking through a Glass Onion“ might mean to see things in a warped and bizarre way. It could also just mean looking at things from the bottom of a bottle (drunk).

I could give several references, but my best advice would be just to look it up anywhere else.

An effect that can occur during an LSD trip where the user sees the world in a similar way to how one would in a video/photograph taken through a fish-eye lens (or from inside a glass onion).

Originated from the Beatles song "Glass Onion" from their white album. It means to overanalyze something that is not intended to mean anything more then what it is. The entire point of the Glass Onion song was to poke fun at all the people who had looked for deep messages in previous beatle songs.
