A word I made up, that I was unaware others made up too. I made it up when somebody I know said that a hot dog looked like a penis. My intention was to use the word as a joke and play a prank on both my brother and my parents by having my brother ask my parents what a weenis was because it sounds like it might be an obscene word, but it really isn't in the general dictionary.
"Hey Dad, what's a weenis?," asked my brother.
"There is no such thing." Said my Dad, frustatingly.
Quietly, I laughed, knowing I had once again succeeded in one of my pranks.
