n. A person who tends to space out often. He or she does not respond when directly spoken to. The space cadet is not necessarily a person of low intelligence or a heavy drug user, but rather one who is so easily lost in reverie that he or she loses all awareness of the surrounding physical world.

When people are in their own little world, constantly "spaced out" of their current surroundings and positions. Often associated with not paying attention, or confusion towards otherwise simple tasks.

Salfordian slang often accompanied by various other slang words, it's normally said in jest but can also be used in anger if the correct wording is used. 'Space-Cadet' is used for describing an Empty headed person that does things so stupid that you can't help but stand in amazement shaking your head thinking "any normal person with half a brain just would not do that'

Not to be confused with 'Space-Man' as that is used to describe a person that has been smoking the widely cultivated plant we all know as 'cannabis..'
