Definition of "Goldfish"

They were both working on their second and The Bad Czech was threatening to break the pub record for eating Goldfish, previously held by the chairman of the division of chemistry. […] He took the little fish-shaped cracker and held it in fingers as big as 50-milliliter test tubes.

For me, Goldfish crackers were always a comfort food growing up.
