If Your An Ordie, Your Asvab Sucks. In reference to the low Armed Service Vocational Aptitude Battery or ASVAB score required to become an Aviation Ordinanceman. This acronym goes along with If You Ain't Ordinance, You Ain't Shit which many AO lifers proudly display on anything they can write. It is believed that the first IYAOYAS reference was made up by some one in the nuclear power field who thought it would be humorous if AO's proudly advertised their level of inteligence.
