My bad

Posted by BGM on September 14, 2000

I've heard this phrase, meaning "my mistake", a number of times in the past year or so. A web search turned up a ref to it, noting that it's common in sports, which seems right -- in this morning's New York Daily News, a baseball player uses it to take the blame for an error.

It sounds like a lame bit of dialect humor -- can anyone shed light?
