I have to echo the hatred of the term "WMD" or "Weapons of Mass Destruction". So overused, and almost glorifying. Sounds like they took the idea out of a sci fi movie.
Dichotomy - this word has its uses, but people use it SO much (the people with whom I discuss things anyways) that it pisses me off. YES THERE ARE A LOT OF THEM. THAT DOES NOT GIVE YOU LICENSE TO USE THE WORD IN EVERY CONVERSATION WE HAVE.
Fundamentally - again, has its uses, but it overused by people that I talk to.
Impossible - this word has no use, except as comical exaggeration.
Haha Pinkie, I say "perdy" and I'm trying to work "I'm fixin' ta" into my vocabulary. I only say them when I'm playing my satirical redneck (makes sense with my being from Alberta), but you'd probably want to kill me after talking for a couple hours.
