Bawdy means humorously rude about sex. A bawdy song, bawdy humour, bawdy jokes.
The humour is the point — bawdy is cheerful and public where obscene is neither, which is why the word suits Chaucer and music-hall songs. It is dated enough now to sound like a literary judgement rather than a complaint.
