I mean, you’re not wrong, but it’s also a legal term. If you pay someone money for something, they can always pay you back. That’s not an irreparable harm.

If (for example) you wanted to say something about someone but you have an NDA that’s in dispute, you could be prevented from saying anything until that’s settled because you can’t un-say something the same way

Unfortunately, so many local burger joints have a “flagship” burger featuring a Sysco patty, cheese, lettuce, tomato, and onion for $17, sides extra.
