look up any word, like fleek:
In any activity if one wins unfairly or portrays the way Michael Phelps won his seventh gold medal in the Beijing Olympics.
In a video game:

Jon: HAHAH! I WON!!!

Molly: No, i won. Look, i shot you by 100th of a second!

Jon: Maaan! you just totally Michael Phelpsed me!
