An employee of Any of the Walt Disney World Resorts. They refer to themselves as Cast Members and their respective places of work as stages. They adhere to a set of rules and guidelines that are fairly secretive to promote great synergy and atmosphere.
Also abbreviated as "CM" or "WDWCM."
I had a really good experience with Josh, a Walt Disney World Cast Member in recreation at one of the Water Parks.
Half-cast is a derogatory term to describe a person of mixed race or ethnicity. It is commonly used to refer to people who are white/black. This term is incorrectly believed to have been adopted from the Indian caste system, but 'Cast' comes from the Latin castus, meaning pure, and the derivative Portuguese and Spanish casta, meaning race.
A "concrete cast on" is another term used to describe a hard penis, BUT can only be used whilst traveling in a motor vehicle (or public transport of any sort).
It is most commonly used after someone has woken up from a short but tasteful nap, where an erection was not expected, or planned.
GUY 1: *asleep*
GUY 2: wake up dude, we've arrived at our destination
GUY 1: *wakes up* oh man I've got a ragingconcrete cast on right now!!
