IDK

"IDK" is a common phrase in the Star empire that commonly mean "I don't know!! Just look, gosh!" This originated a couple billion years ago when something starting choking and said "I-D-K" before dying right there on the spot. Since then, the phrase has gone into common use, and variations have developed, like saying IRDK, which means "I REALLY don't know!!! Look right now!" "IDK" is also considered an official acronym.
