Menstruating; on one's period. British, slang, vulgar
"I have no problems fucking wimin on the blob. But some of them do"
2
Of begging etc.: performed by speaking to people, not by writing letters. UK, obsolete, slang
"With this excusable class, however, I have not now to do. Of professional beggars there are two kinds—those who ‘do it on the blob’ (by word of mouth), and those who do it by ‘screeving,’ that is, by petitions and letters, setting forth imaginary cases of distress."

(menstruating): Apparently a reference to the blobbing (i.e. dripping) of menstrual blood, likely following the model of on the rag.
