means A style of sushi where a hand-pressed oblong of vinegared rice is topped with a slice of fish or other seafood, usually with a touch of wasabi between them.

from From Japanese nigiri, meaning 'grip' or 'grasp,' from the verb nigiru, 'to squeeze' or 'to mold by hand' — a nod to the way the rice is shaped firmly between the chef's palms. The fuller term is nigirizushi. The style is often credited to 19th-century Edo (old Tokyo) street-food stalls, where it was served as a quick, handheld bite — fast food for a fast-growing city, long before 'fast food' was a phrase anyone needed.
