Da kine (/də ˈkaɪn/) is an expression in Hawaiian Pidgin (Hawaii Creole English), probably derived from "that kind", that usually functions grammatically as a placeholder name (compare to English "whatsit" and "whatchamacallit").
Unlike other placeholder names in English, however, which usually refer specifically to a device ("gizmo" or "widget"), person ("so-and-so"), or place ("Anytown, USA"), "da kine" is general in usage and could refer to anything, any being, object or concept.
It can be used to refer to something nonspecific, or given enough context (especially when used in conversation between native speakers of the dialect) to something very specific.
"Da kine" is probably the most identifying characteristic of spoken Hawaiian Pidgin, and certainly the most versatile.
"Da Kine" comes from "the kind" or "the thing" and is used as an extremely vague, yet simple explanation of an action or object when something's specific name is unknown or cannot come to mind.
