The term "Billy Martin" was used by Daniel Ocean in the movie Ocean's 13. It refers to baseball player Billy Martin, fired then rehired by Steinbrenner a couple times.

It means giving a second chance.

Manager for the New York Yankees, 1975-78, 1979, 1983, 1985, 1988. One of the best managers ever because of his fiery temper, take-no-prisoners approach, and fights with the Boss. Died tragically in a car crash on December 25th, 1989.

NOT the guitarist for Good Charlotte.

Manager of the New York Yankees (AKA the worst team ever) in the 1970s and 80s. He was fired and re-hired almost half a dozen times by erratic lunatic/Yankees owner George Steinbrenner.
"Today in sports, George Steinbrenner just fired Billy Martin again. The Yankees haven't won a World Series in the 80s, and Steinbrenner's finger's on the button again!"

Billy Martin is also a term used for giving someone a chance to make something right or to make ammends. Yes it is a person, yes it is a term. Check out Ocean's Thirteen for that, though I believe the term came before the movie.
So your offering me a Billy Martin? Well I pass.

I know it's all been said before. A lot. But... he's the absolutely gorgeous, lovely, talented guitarist of the brilliant Good Charlotte. He's a really good artist as well. I love him, like a lot of people do. He's amazing. He really is.
Billy Martin is an example of amazing beauty, talent, niceness! That's what he's got, and much more!

a talented guitarist of good charlotte. he's really creative, who even has his own clothing line called LeVel 27. He also designed most of the logos on GC's merch. Not only is he artistic but he has a great passion for music(including his fave band silverchair), playing video games, and drawing cartoons. Best of all he loves animals! keke.
