-zilla is an English slang suffix, a libfix back-formation derived from the English name of the Japanese movie monster Godzilla. [1] [2] It is popular for the names of software and websites. It is also found often in popular culture to imply some form of excess, denoting the monster-like qualities of Godzilla.
This trend has been observed since the popularization of the Mozilla Project, which itself included the Internet Relay Chat client ChatZilla. [3]
The use of the suffix was contested by Toho, owners of the trademark Godzilla, in a lawsuit against the website Davezilla [4] and also against Sears for their mark Bagzilla. [5] Toho has since trademarked the word "Zilla" and retroactively used it as an official name for the "Godzilla In Name Only" creature from the 1998 Roland Emmerich film. [6]
