What does gullish mean?
Gullish describes someone who is foolishly credulous and therefore easy to deceive. The word carries a distinctly negative judgment: it suggests that a person has accepted a promise, opportunity, or explanation without enough caution or critical thought. Gullish can describe a person's nature, as in a gullish investor, or a decision or action that reflects such credulity. It is more literary than the everyday word gullible and often sounds more pointed because it implies both foolishness and susceptibility to manipulation. In modern English, gullish is used in British and American writing, especially in journalism, commentary, and formal discussion of financial, political, or commercial errors. The term is related to gull, an older word for a simpleton or fool, and to the better-known adjective gullible.

Where does gullish come from?
Gullish was formed in the early 17th century from gull, meaning a fool or simpleton, together with the suffix -ish. The development was therefore part of the older English pattern of forming descriptive adjectives from nouns. The related words gullible and gullibility later continued the same gull root, while gullery belongs to the separate but historically related vocabulary of the seabird.
