<networking, abuse> (Possibly influenced by British slang
"plonk" for cheap booze, or "plonker" for someone behaving
stupidly; usually written "*plonk*") The sound a newbie
makes as he falls to the bottom of a kill file. While this
term originated in the Usenet newsgroup
talk.bizarre, by 1994 it was widespread on Usenet and
mailing lists as a form of public ridicule.
Another theory is that it is an acronym for "Person with
Little Or No Knowledge".
