1) Movie blabbing - I'm glad that you enjoyed the latest action film, really, I couldn't be more happy for you. In fact, I'd like to see it myself. But please, don't be an idiot and tell me how the movie ends, or even that it has a "twist ending." Do you know why a twist ending works so well? Because you don't see it coming! But, thanks to you, the surprise is already ruined.

2) Chewing with your mouth open - This is a situation where two good things can make a horrible habit. People like to talk, and people like to eat, but the combination of the two? Not a lovely sight. So please, chew with your mouth closed, because I'm really not that interested in seeing what half-chewed food looks like.

3) Arrogance - We all know that one person who is never wrong, and who somehow always knows the answer to everything. Nevermind the fact that they're never willing to prove it, and that any accomplishment you've achieved has already been surpassed by them. It must be nice to be the arrogant person described here, but for the rest of us, you're just another person annoying the heck out of all of us.

4) Apologizing constantly - Overly apologetic people are at the other end of the spectrum. Whether they constantly apologize out of the need for attention, or a horrible sense of self-worth, it matters not. It's annoying. Don't consistently apologize for asking a question, or for being two minutes early. Have a little bit more pride, and two or three fewer apologies.

5) Flushing - I'm not sure if women run across the same issue, but what's with the amount of men who refuse to flush? Whether it's the urinal or the toilet, it appears that men have no idea how to use a handle. We get it, you don't want to touch a handle that someone else touched. Guess what, I don't want to piss in someone else's mess either. And while we're at it, if you're so concerned with your precious hands getting something on them, wash them before leaving the restroom! (A recent study shows that one-third of men do not wash up before leaving a restroom.)

6) Lying - Some people just cannot tell the truth. No matter how unimportant the story, you've always got to put your own spin on it to make it into something extraordinary. Seriously, your ability to eat a hundred hot dogs in less than four minutes may sound amazing to you, but it's just another lie to me.

7) Heckling - There's a fine line here, depending on the situation. Heckling a comedian? Not funny, and makes no sense considering you paid to see them perform. Heckling an opposing sports team? In some situations is allowed, but not as much when you're heckling the home team. Feel free to cheer for whichever team you root for, but don't cross the line into obnoxious behavior (I'm talking about you, stupid Rockies fan sitting behind me at Game 1 of the NLCS in Phoenix).
