1.
A way of admitting a mistake, and apologizing for that mistake, without actually apologizing. The best definition I ever read of this, now paraphrased:

"I did something bad, and I recognize that I did something bad, but there is nothing that can be done for it now, and there is technically no reason to apologize for that error, so let's just assume that I won't do it again, get over it, and move on with our lives."

Ruder than apologizing, but with the same meaning: a flippant apology.
"You just spilled your beer on my term paper!!"
"Er... my bad."

"Hey, you spilled my Coke all over me!"

"Oh. My bad."

A term currently used when a mistake is made on your part. Allegedly originating from an unamed African Basketball Player in the 1980's (who spoke very poor english)who said it after missing a free throw. Several Sportscasters heard the phrase and used it as a joke until it became a part of popular culture.
