kupinda mumunda mevanhu
means to irritate someone (or a group of people), especially by interfering with something that is their responsibility or getting involved in matters that are too personal.
For example, when you try to insert yourself in a lovers' quarrel instead of just minding your own business and of course, drinking more water. After all, it's good for you, isn't it? Because when they get back together they will blame you for trying to ruin their relationship. Go figure!
Note: When translated loosely kupinda mumunda mevanhu means "to trespass on someone's farm or plantation."
