And what exactly is "Dee", slang or what? I googled it and didn't find anything interesting or uninteresting except for surname, given name, river.
"D is the 4th letter in the alphabet. Its normal name in English is dee."I don't get what all the fuss is about. What the hell is Dee supposed to even mean?
It's a joke. The Simpson did it. Homer's middle initial 'J' stands for Jay.
