Profligate (adjective): recklessly extravagant or wasteful in the use of resources.
” And it’s also why if you’re profligate with information about yourself, you have precious, little to offer someone really special.”
I encountered this word while reading the article, “WE want Privacy, but Can’t Stop Sharing” by Kate Murphy. This is my first time encountering the word so before looking up the definition, I searched for synonyms so I can find a word that I do know with a similar meaning. I came across words such as wasteful, extravagant, and prodigal. Basically means someone who spends money wastefully.
