ZOMG

 

abbreviation

informal
  • (used especially on electronic message boards as a sarcastic comment on an inexperienced or overenthusiastic poster) oh my God!: ZOMG!! I finally managed to reformat the file

Origin:

early 21st century: perhaps in reference to fast or careless typing of OMG, during the course of which the shift key is missed and the 'z' key pressed instead.
