1. My bad
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.”
