Facebook missile - A Facebook missile is like a cruel enemy who posts or shares

A Facebook missile is like a cruel enemy who posts or shares your stupid stuff just to make your life a total mess.

My ex posted my old text messages and said I was 'a disaster.'

My friend shared my failed attempt at a TikTok dance and called it 'the worst ever.'

My teacher shared my essay about my pet goldfish and said I was 'a total waste of paper.'
