When your lazy ass son walks around with his socks hanging half way off his feet. The sock part hanging off the end of the foot is called a : 'dingledong'.
It actually drove my 7 year old daughter nuts, and she actually came up with the word 'dingledong'. We happened to be talking about what a dingleberry was before hand. I guess that was her inspiration.
Austin pull up ur damn socks you have dingledongs.
