1. Someone says to you;
Oh no you didn't. You reply,
That's How I did. The phase should be stated with attitude.
2. Someone says to you; For Real. You reply,
That's how I did, as if you were saying, yes that's true.
3. Someone says to you; You been with my sister and my girlfriend? Respond loud and proud That's How I did and
I'd do it again!
