Used as a descriptor for a very inexpensive and shoddily-made product of non-US origin, such as products manufactured in China, Taiwan, or Hong Kong
From a product reviews website:

"Eight of the twelve units purchased were nonoperational; but this was somewhat expected of a very inexpensive product of non-US origin - sometimes known as the "Hoo Phlung Pu" brand."
