One Down

the opposite of one upping someone, trying to match a complaint with and even worse grievance.

Person A: I don't think I did to well on this test!
Person B: Well, at least you studied. I didn't even know we had a test today.
Person A: Why are you always trying to one down me, let me have my moment.
