One of my all time favorites, to predict or describe what I believe will be the outcome of something, is "At The End Of The Day"
Also, many times if I refer to someone as a "Fuck", instead of referring to them as a "Fuck", I will refer to them as a "Fucknoid". That saying was picked up by a former friend at college.
Two other favorite sayings, also picked up from past friends, are "BFD" (Big Fucking Deal, of course) and "NFW" (No Fucking Way) In fact around the time of Y2K, I happened to come across a shirt that said "Y2K BFD". I had been saying "BFD" for probably 10 years before, so you know I just had to buy that shirt.
Sometimes, to refer to a person who I don't think highly of, especially intelligence wise, I will refer to them as a "Schnook". I also picked that up in college, from friends who decided that "Schnook" sounded a bit nicer than "Moron" or "Idiot", terms which I only use if someone is a true dummy.
Then, of course, there is the always favorite "Schmuck" or "Putz", and also one borrowed from my mom, Putzyana. I dont know where she got that one from!. Again, often used by me as interchangable, or instead of, Moron, or Idiot.
That's about all.
