Chow

Chow \CHOU\ , noun;
1. Food, especially hearty dishes or a meal
verb phrase;
1. Chow down: To eat; eat a meal, especially the main meal of the day

This American English word is first attested in 1856 from a Chinese pidgin English word, chow-chow, that originated in California around 1795. Chow-chow meant "food" and was a reduplication of Chinese cha ("mixed"). The dog breed chow dates to 1886 and is of unknown origin, though folk etymologies suggest it has something to do with Chinese practice of eating dog meat.
