look up any word, like fleek:
 
1.
The word 'netbanger' is formed from two nouns: 'net' + 'banger'. The 'net' part is simply a shortened version of the word Internet. 'Banger' is a noun that literally means someone or something that makes a bang. Its precise and intended meaning is actually derived from the Icelandic word, banga, meaning 'to hammer'. In combination, the two nouns produce the new noun, 'netbanger', which denotes irreverence, a degree of iconoclasm, and free thinking. The name netbanger does not have negative connotations.

The term 'netbanger' was first coined in 2000 by the owner of the domain of the same name.
Mannie was somewhat of a netbanger; his personal views were unashamedly undisguised, which often proved controversial.
