Linguistic Pet Peeves

This is just a list of those phrases that people say, usually without thinking about what they really mean, that I find irksome. If you use them, it by no means means that you're a bad person, it merely proves that nobody really thinks about everything they say.

• "I'm going to let you go." People use this often to end a telephone conversation, and taken literally it's sort of a nice gesture. Unfortunately, most of the time that it's said, it's said disingenuously - you don't "let someone go" because you know they have something to which they should attend, but because you have something to which to attend, but you instinctively don't want to be the one responsible for ending this stimulating conversation.
  
• "Let me know." I use this all the time, and I hate it. It's a bizarre, polite euphemism for "tell me." Please, good sir, I do beseech thee, permit this poor supplicant the awareness of that which you have to impart. Just answer my damn question!
• "Amazing." The rampant overuse of this word is an example of meaninglessness. For many people, calling something "amazing" is no more descriptive than giving it a thumbs up. It has lost its actual meaning of describing a thing that amazed the speaker. Was that book really amazing? Did it actually amaze and astonish you? Were you dumbfounded? Or do you simply lack the vocabularly or at least the assiduousness to praise it in a more precise manner? I would wager, in most cases, that it's the latter.
• "Standing on line." This I believe to be a Northeastern (aka, Yankee) turn of phrase. This, to me, is an alternate form of "in line." Are there lines painted on the ground in certain parts of the country to facilitate enqueueing? I've been around a bit, and I've never seen them. I've waited, people seriatim, in a lot of places, and I've never seen a guide marker underfoot. The line is an imaginary one, formed by the people waiting. I can't see how anybody is "on" that line. But they sure seem like they're "in" it, inasmuch as they're the constituents of it.
  

I'm sure our devoted readership has other such phrases that it deplores, rationally or otherwise. As always, please share, and we'll include.
