Mars

To cause someone or something to either succeed or to fail; to cause either a positive or negative outcome for someone or something. Primarily heard in UK. When you're young, you often think that big obstacles will either make or mar you, but as you get older you realize that it's not that simple. It all comes down to this penalty shot. One kick will make or mar their season.

To scuff, scratch, dent, or otherwise ruin the smooth surface of something. A noun or pronoun can be used between "mar" and "up." You're going to mar up your screen if you carry your phone around in your pocket without a protective cover of some kind. Look at my brand new car! Someone scraped along the side and totally marred it up!

to dent or scratch something; to harm the smooth finish of something. Please don't mar the furniture up. Don't mar up my desk.
