A nick-name for Roger Federer. The greatest tennis player and gentleman of all-time. When he swears at the umpire, people take his side because he never loses.

Dude 1: When I first saw Darth Federer's shot I thought it was clearly out but the I realized that he never loses so it must have been in.

Dude 2: This is true. His presence on the court is immaculate.
