Riding my ass 

The experience of having a person, most likely driving a large truck or SUV with their high beams on, tailgating you at night when you are clearly exceeding the posted speed limit.

Dude, this chode was riding my ass the whole ride home even though I was going 20 MPH over the speed limit!

An annoying and burdensome, but important responsibility or concern that is hovering over you that you have to bear and deal with, albeit begrudgingly.

My job is so stressful because of all the big clients I got riding on my ass.
