Tiki is a type of decoration that comes from the Polynesian islands. It usually means statues or carvings of gods or other important figures. These decorations are often made out of wood or stone and can look very scary or funny. People like to put them in their homes or in places like tiki bars to make the place feel more tropical and relaxed. Sometimes people even use tiki decorations when they throw parties or go to events like a luau, which is like a big outdoor party with lots of food and music. So, tiki really just means things that come from Polynesian culture and are often used to decorate and celebrate good times!
