People love to bitch about language so I will too even though I figuratively don't care when words evolve and meanings change because it is inevitable.
  1. Irony
    Are you sure the situation was ironic? I always forget what that word means so you are on your own but I am going to assume your using it wrong.
  2. Good
    Just trust me that you probably mean well.
  3. Nerd/Geek/Dork
    Why do these words all seem to have true same colloquial meaning? Come on that is annoying.
  4. Awful/Awesome
    What full of all is bad but some of awe is good? Make up your mind!
  5. Literally
    Oh really you literally don't know or maybe even care what this word means.
