look up any word, like hipster:
 
3.
adj.; when used as a suffix for a proper name or specific entity, becomes part of that noun.

Derived from Godzilla, the gargantuan reptilian star of Japanese "B" horror movie genre. Introduced in 1954 as "Gojira", Godzilla is the embodiment of all that is massive, destructive, and extremely difficult to defeat. Ergo, "'zilla" in both the stand-alone adjective and suffix forms represents those same charecteristics. Linguistically, the "z-l" combo has stronger audiological punch than "j-r", thus giving "'zilla" more connotative power than "'jira".
The neighborhood chug-a-lug champ might be referred to as "Beerzilla."

The creator of Micorsoft could easily be dubbed "Gateszilla."
