A phrase to insult someone without saying anything wrong, thus letting them use their imagination on how insulting you meant to be.
My music recording teacher always calls us fops, sops, and simpltons. I went up to him and said "Your such an insert word here" he then gaped at me and told me i was mean. (he laughed a few minutes later)
use this if you cant think of a word but you want to buy a fricking mug in this website and recall if your life has worth to society and the universe itself
