[wine sense fr French vin blanc, ''white wine''; second sense perhaps fr the dull sound plonk]
plonk in Technology
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 Usenetnewsgroup news: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". (2002-01-18)
