Le Taki Taki occurs very often. It is when Someone acts or say something that is either very dumb,stupid and if it dosen't make sense. And if someone says it to you they are either trying to say dont be a dumb or stupid person or act very dumb because they are protecting you from it.
But for a joke it could mean someone lowers their body and scream and make weird sound, and they would be slapping their thigh this is because they may have become addicted to the taki's chips or they are very lonely and want attention by dancing.
Ex 1: "Dad: Son what is Target ." Son: Wtf dad Le Taki Taki it's a common thing."
