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.
A double-level euphamism used by a recently dumped male to refer to his newly acquired mastubatory status whilst masquerading as the person who chose to end the relationship. On the surface level, this allows the male in question to save face in front of his friends, by appearing to remain in control of his own sexual destiny. At a deeper level, his return to the world of self-service and tissues was not of his choosing.
Dumped dude's mate: "So did you sleep with your gorgeous ladyfriend last night?"
Dumped male - Level 1: "Nah! Dinged it off!" - "I have dumped her"
Level 2: "Nah! Dinged it off!" - "She's dumped me so I had to have a wank"
adj. A meshing or fusion of both the words dingle berry and dork. Used to mainly describe someone who completely fits both word descriptions. In a literal sense, a very smelly person who looks like a whales penis.
