Mort: Someone who lacks sense of life, looks dumbfounded, and has only a limited ability to learn and understand. (urban slang)

Elvis: A famous rock star

Enstein: A famous physicist

Amanda: ???

Mort, Elvis, Enstein are referencing things I've heard of before. What is Amanda referencing? is there some famous person named Amanda? Is it slang I'm unaware of?

She is not familiar because she is referencing things that are rare. You haven't seen an "Amanda" because she is rare. Just like common sense.

Amanda is clearly the most beloved of those four. ;)
