From The origin of 'my bad':
The best evidence obtainable at present points to Manute Bol (above), the 7'7" Sudanese NBA player whose native tongue was Dinka, as the inventor, sometime in the 1980s, of this nowââ¬âubiquitous phrase.
Finally, someone to blame for this incredibly hard-to-hear phrase. Yeay. I keep wanting to say "my bad what?", since my and bad are both adjectives there to my ears.

I heard it was a reanalysis of 'M (Am) I bad.
Apparently this was used in some TV show. But perhaps I'm just inventing that part.
Could be both explanations are correct

The comment with the article is noteworthy: 'These are white people making these "reports" of what they heard??'
