Pencey Prep
1. Name of a (fictional) school that the character Holden Caulfield is kicked out of in the classic novel "The Catcher in the Rye" by J.D. Salinger.
2. Name of a band formerly fronted by Frank Iero, who is one of the guitarists for internationally popular alternative rock band My Chemical Romance, the front man for hardcore outfit Leathermouth, and owner/founder of Skeleton Crew Records and Clothing Label. The book came first, so it's assumed that Frank and his band mates are fans of "The Catcher in the Rye".

One of Pencey Prep's most popular songs goes by the title "The Secret Golfish"...yeah, I don't get it either. 
Person 1: So there's this band Pencey Prep who are really awesome and I think their name is just so creative!
Person 2: Uh, yeah, they're pretty good. But Pencey Prep was taken from this old book...
Person 1: *kills Person 2 with blunt object*
