I'll see you a walla and raise you one.
I hate hate HATE lol added to the end of every sentence. I have a friend who will complain about how terrible her life is and every sentence ends with lol.
"Do you want to....?"
No. I don't. And I usually answer in such a manner.
Also, I can't stand it when bosses/managers/higher-ups start with saying "We need to..." Okay, maybe I'm just being difficult here, but if you say WE, then you need to take some ownership of whatever it is you're telling everyone else to do. If "we" need to get all these bins filled with product, don't then stand by and watch as everyone else fills bins with product and you don't.
Then again, most of these I use with my friends/family, but it's all a matter of audience. I don't use a lot of these here, and if I know that someone is exceptionally bothered by something, I try to remember not to say it around them.
