Morphology

my + bad

Although the parts 'my' (possessive) and 'bad' (negative quality) give a partial hint that something about the speaker is negative, the jump from 'bad' to admitting responsibility ('my fault') is idiomatic and sociolinguistically marked. A B1 learner who knows both words may guess a negative comment about the speaker but will not reliably infer the conventionalised apology/acceptance-of-blame meaning without prior exposure, so the expression is partially but not fully transparent.

Etymology

The phrase my bad likely comes from casual American games like pickup basketball, where a player who made a mistake would say my bad, literally calling their action my bad. One popular story says this short line became an easy way to admit a mistake, so today it means 'my fault' or 'sorry'.
