Just another Perl hacker, or JAPH, typically refers to a Perl program that prints "Just another Perl hacker," (the comma is canonical but is occasionally omitted). Short JAPH programs are often used as signatures in online forums, or as T-shirt designs. The phrase or acronym is also occasionally used (without code) for a signature.
JAPH programs are classically done using extremely obfuscated methods, in the spirit of the Obfuscated C Contest. More recently, as the phenomenon has become well-known, the phrase is sometimes used in ordinary examples (without obfuscation).
The idea of using tiny Perl programs that print a signature as a signature was originated by Randal L. Schwartz, in his postings to the newsgroup comp.lang.perl.[1] He wrote many of the JAPHs which are shown below.
