StudlyCaps (or perhaps StUdLyCaPs) is a variation of CamelCase in which the individual letters in a word (or many) are capitalized and not capitalized, either at random or alternating in some pattern.

According to Eric Raymond's Jargon File (http://catb.org/~esr/jargon/html/S/studlycaps.html) "ThE oRigiN and SigNificaNce of thIs pRacTicE iS oBscuRe." It appears to have been popularized among adolescent users during the BBS and early WWW eras of online culture, as a form of rebellion against the rules for proper capitalization of names and sentences. Unlike the use of all lowercase letters, which suggests laziness or efficiency as a motivation, StudlyCaps requires additional effort to type, either holding and releasing the Shift key with one hand while hunting-and-pecking, or alternately pressing one Shift key or the other while touch typing.

It may perform a similar social function as the reduced legibility of the highly stylised script commonly used in graffiti. The overt defiance of rules distinguishes it from most forms of CamelCase, which - despite their defiance of traditional typographic rules for language - are noteworthy for their adherence to authority-established standards specifying which letters are to be capitalized and which are not.
