Viet is a shorter term for one who is of Vietnamese descent. Vietnamese and other cultures name their children by this term as well. Those who are named Viet are very passionate. They are silent at first glance but very fun once they warm up to you. Viet's can have tempers and are not afraid to voice their opinion to someone close to them. However to strangers they remain quiet. Their facial expressions don't necessarily match their emotions. They could be content on the inside yet their face could mean danger. Those named Viet are not necessarily the brightest crayon in the box, however they will do anything to make their loved ones happy. Don't misuse their trust or let them down, because they can easily fall down the wrong path. If they've wronged you in some way, they will do all it takes to redeem themselves.
The word VIET is not just a shorter way to say Vietnamese. It can be an actual name. I once knew a guy named Viet who was very quiet and mean looking. But inside he was a softie! Viets are very nice people!
