derder

Noun. Cylindrical light-stock cardboard tube used to wrap toilet paper and paper towels, among myriad other paper and card stock products. Once the paper is exhausted and it is no longer used in its original capacity, it is used to trumpet one's voice around the room or venue in similar fashion to a megaphone.

My dad sounds so ridiculous when he uses that derder to make a duck call.
