Stereotypes

Python fag: uses Python because he can't comprehend a language that is actually useful. Listens J-Pop and anime music.
C programmer: Older programmer that thinks there could never be anything better than C, even though C's standard library is woefully inadequate. Listens to classic heavy metal (Megadeth, Anthrax, Iron Maiden)
C++ programmer: Learned it in college and hasn't yet needed to change to anything else. Listens to classic rock (Rush, Jethro Tull)
Haskell fag: "I'm not gonna use those shitty mainstream languages, man! Those fucking sell-outs." Listens to shitty indie music and complains that no one understands them.
Java fag: Learned Java in college, can't learn anything more useful. Listens to ClearChannel radio.

Am I missing anything?

The Lisp Fag knows all. Has read PAIP, SICP, CLTL2, Hyperspec, TAOCP, AIMA and all similar literature. Knows more than your professor of Computer Science. Has IQ of 150. Totally pwns you at anything.
