I know some informal words for disappointing people/doing something unpleasant to them, but I want to make sure that these sentences sound natural:

"I don't believe our teacher is gonna give us an exam today! He wouldn't let us down!"

"Our teacher wouldn't give us an exam today! That'd be a bummer!"

"Did John (a friend we trusted) really do that to you? What a bummer/letdown!"

If they sound awkward, what other words could I use in these situations?

  • Seriously? You know how to use the (weird, imho) expression "dick move" in three different examples, but you don't recognise "bad move" as a non-profane alternative? Or maybe "stupid move" - I don't even know exactly what you want it to mean. Jan 28, 2015 at 21:45
  • @FumbleFingers That's why I'm here: to learn. Thank you for your suggestions. In the last sentence, I meant that somebody made offensive cartoons of Bob. I find them stupid and think that they may hurt his feelings.

  • Perhaps for that specific context an idiotic move might be better. But then again it might be even better to forget about adjectivally modifying the word "move", since it's not really relevant to the context. "That's puerile!", or "That's childish!" might have greater force, since they both rise well above the "playground swear-words" level of things like "Dick move!" Jan 28, 2015 at 22:08
  • ...note that I have closevoted "Primarily Opinion-based" because you've obviously got at least two significantly different example contexts. If you want a context-specific alternative expression, you need to give us an exact context (is the "bad move" bad because it's stupid, inconsiderate, very undesirable for those affected, or what?).

    @Stephen: I'm not saying you're wrong with that distinction, but I would take some convincing - especially about the idea that an attacking play in chess might be called a "dick move". I might even need convincing that people who use the term actually recognise good/bad moves in chess. Jan 28, 2015 at 22:55

You could say something like "This really sucks" or "I'm very disappointed".

  • So the verb "to disappoint" is also used colloquially? In my native language, it sounds more formal.

  • Well it is slightly more formal but it would sound more normal than "he wont let us down" Does this help? Jan 29, 2015 at 0:07
