What is De Jong?
1.
A particular type of behaviour that includes tendencies to stalk lots and lots on websites such as bebo and facebook, and enjoy typing the words "lol" and "hehe" in internet conversations. It is also a type of person who has a massive scar at the top of their legs, which most other people would call a fanny...but he calls a unicycle injury
Brian: Hey Jamie, what are you doing on that computer?
Jamie: Not much, just a bit of de jong-ing!
Also, can be used as a vile insult, such as:
"Stop being a de jong"
