neologism
A neologism (pronounced nee-AH-low-djism) is a newly invented word or term. Neologisms would seem to occur at a greater rate in cultures with rapidly changing technologies and with greater means for information dispersal.
A neology is, according to our Webster's, the use of a new word or the use of an existing word but given a new meaning. A second meaning given by Webster's for neologism is that of "a meaningless word coined by a psychotic."
