What is On The Blob?
1.
When a girl is on the blob, that means she has her period.
Dis bitch's a lil' bitchy, I fuckin' think she's on da blob.
2.
A crude expression for a female on her period used by immature boys who don't realise that a female is stressed when she is not on her period (hence the term PMS - PRE menstrual tension) thanks for reading.
"Naff off Dave."
"Oooh! Let me guess - you're on the blob!" Uh, no!
