Someone with a very small penis is called Vadong. You ain't getting any vagina, because your penis is so small that no chick wants you near her vagina - - you are Vadong.
My buddy picked up this hot chick at the pub last night, but when he took her home, he pulled down his pants and the bitch said, "What the Fuck?, get outta here, you are Vadong."
A more feminine way of talking about a dongle, which is a hardware device attached to a computer without which a particular software program will not run: used to prevent unauthorized use.
Dick: I can't find my dongle. I hate it when my colleagues use mine without asking.
Jane: My vadongle is missing, too. Someone must have taken it to show a video.
