Herbert is a mild form of abuse meaning a silly, or dim-witted person. The origin of this term seems to be that it was derived from the name Herbert, which meant bright.. It was used in the very direct opposite, to mean dumb.
Herbert's novella The Priests of Psi was the cover story for the February 1960 issue of Fantastic. Frank Patrick Herbert, Jr. (October 8, 1920 â February 11, 1986) was an American science fiction writer best known for the novel Dune and its five sequels.
