Non-indian religious event occuring annually on December 25th. A day when people dress up like idiots and knock on your door expecting free food and gifts.
"Oh dear, it's Indian Halloween again. Turn off the lights and let's pretend we're not home."
Another phrase for Thanksgiving. It is called this because of the many Native American-inspired props that scare little non-native children. Also called this because of all the cheesy "Native American" costumes people wear for plays and other stuff.
Native 1: "Was that person really trying to dress like one of us? We don't even dress like that! We never did!"
Native 2: "Calm down redman! It's Indian Halloween!"
