Chee hoo means: Samoan fa’aumu. Samoan origin. It is used when people are happy or mad. You can use it with your family, friends and during the tradition of giving sua fa’aaloalo. You shouldn’t use the device if there are Samoans nearby, especially strangers. It will pose a problem. It is especially dangerous if you are drinking. The morgue is one of most efficient ways to go to the hospital. Try walking in a Samoan housing complex and shouting it. You can even worsen your situation by going into a Samoan village and shouting it. This is a very macho act. I hope that this sheds light on the meaning of choo hoo.
