You're presenting awards at a company-wide end of year party. You have to call out someone's name that's written down, but the spelling is very tricky. You don't think you'll be able to pronounce the name correctly. Before saying the name, you say:
I know I'm going to mangle this...
announcements, future, pronunciation, speech 
Your name is complicated to pronounce for English speakers. You're introducing yourself to someone that you just met, and explaining how to pronounce your name. You say:
I know; it doesn't exactly roll off the tongue.
apology, idioms, pronunciation, understatement, 日本語サポート 
You're sitting in the window seat in coach on an airplane. You need to go to the restroom, but the person sitting next to you is taking up too much space and you can't get out. You say to him:
Excuse me. Can I slide past you?
This is what you say to strangers to get their attention:
Excuse me, we're taking up donations for the Haiti Relief Fund. Do you have a moment?
Excuse me. Would you mind watching over my stuff for me for just a minute?
The "e" at the beginning is unstressed, so sometimes it sounds like "Scuze me"
This is a polite question to ask when you need to get into a place that's being blocked by someone's body. Some other examples of situations that you can use this in are:
"Can I slide past you?" is a friendly way to ask this. It sounds friendly because the word "slide" sounds so smooth and easy. It's like you're saying, "Can I go past you quietly and without bothering you much?"
If you're more annoyed or if you're a loud and aggressive person, you can ask like this:
Can I get by?
