The idiom “a short fuse” means to have a tendency to become angry very quickly or easily. It is often used to describe someone who has a bad temper or a quick temper. For example, you could say:
- He has a short fuse and he always loses his cool when things don’t go his way.
- She’s on a short fuse today. Don’t say anything that might upset her.
- I don’t want to work with him. He has a very short fuse and he can be very rude.
The idiom comes from the idea of a fuse being something that can explode or burn out if it gets too hot or too long. A person with a short fuse is like a fuse that can blow up or catch fire easily.
