My friend noted in classroom that "to zap" means "to destroy something unintentionally".
I can't find anything about it in dictionaries. They just say it can mean to kill someone or get rid of someone.
I dare to ask you about your opinion guys
Have you looked up "zap" in the WordReference dictionary? If not, just type it in the box at the top of this page.You might also look here: http://www.etymonline.com/index.php?term=zap Your friend's definition is not very good.
