Pertaining to, speaking of, or just downright calling someone retarded or a retard. Originating and somehow managing not to venture outside of the boundaries of the Athens-Clarke County Public School System in Athens, GA, lump lump has been used for generations of students when describing special needs kids, short buses, and teachers who can't teach for shit.
Damn, there goes the lump lump bus. I hope they don't start throwing poo at us.

When a group of friends have an inside joke, and another person is asking what's so funny. Definition comes from the movie 'Menace to Society'.

Caine: You don't wanna go out like Willy Lump Lump.
Sharif: Who is Willy Lump Lump anyway?
Caine: Ah man, don't worry about it, it's an inside thing.
"What are y'all laughing at"?

"It's a Willy Lump Lump, don't worry about it. You wouldn't understand."

Person 1: What's so funny?
Person 2: (they smack their lips and look person 1 up and down crazy-like and says) Willy Lump Lump

This is a man who says "Oh my god" and "You're kiddin' me" a lot. He dances like Carlton, mostly to the song "Apache" by Sugar Hill Gang. He eats excessive amounts of White Castles and irons his underwear and socks every day.
"Oh my god, I'm a regular willy lump lump. I can't wait to go to White Castle today, right after I finish ironing these tidy whiteys. I hope I hear "Tonto, jump on it" in the car on the way there!"
