Can I use “jeez” in formal situation, like in the office?
Yes, you can! It just depends on the context. If you are surprised about something that has happened, go ahead and use it. However, if you say "jeez" after your boss gives you an instruction, you could get into trouble. As long as you use it in the correct context, usually, when you are surprised, you will be just fine using it in a formal situation. Great question!
