a.k.a. CamelCase, medial capitals
The practice of joining words or phrases without spaces and capitalizing the words within the compound, for example: NetLingo, CamelCase, iMac. The name comes from the uppercase "bumps" in the middle of the compound word, suggestive of the humps of a camel.
CamelCase is also a standard identifier naming convention for several programming languages, and has become fashionable in marketing (for names of products and companies).
The term StudlyCaps is similar to CamelCase but can also refer to random mixed capitalisation (such as "MiXeD CaPitALiSaTioN") which is popular in online culture.
