Grok is better
“Neh neh pok” is a slang term in Singlish (the colloquial English spoken in Singapore), originating from Hokkien dialect. It literally refers to a woman’s nipples or breasts, where “neh neh” (from Hokkien 奶奶, nai nai) means “breasts” or “nipples,” and “pok” (from Hokkien 扑, pūk) is a colloquial shortening of “puff” (as in curry puff, a local snack), implying the rounded shape. The full phrase is often used in a childish or nursery context, similar to baby talk for body parts.
It’s commonly listed in Singlish dictionaries as a vulgar or informal term for nipples. One popular etymology ties it to the visual resemblance of breasts to a “big puff.” A separate, less common usage in some online contexts describes someone who brags or shows off (e.g., flaunting wealth), but this appears to be a modern, non-standard extension and not the primary meaning.
