A situation that causes problem for you / A lot of trouble that annoys you
I hope taking care of my dog while I’m away won’t be too much a hassel for you.
I’m going to save myself the hassel of going to court, instead just pay the fine and get away.
My boss wants me to take over my co-worker’s responsibilities on top of my own, during her sick leave. It’s going to be such a hussel !
