one-up(s)manship(redirected from upsmanship)
The act of trying to outdo or be more successful, admirable, or respected than someone else. If the members of our Congress were less involved with political one-upsmanship, we could have passed several bills by now that could be stimulating the economy. I've never seen someone more devoted to one-upmanship than Tim. No matter what you say you've accomplished, he'll tell you about something even more impressive he's done.
