It's a continuation of the popular game of "sticky biscuit" where men masturbate over a biscuit inserted in a lady's vagina. Except in this version the lady is on her period.
"Oh man, you missed a great game of jam on a biscuit last night. That menstruation sure tasted good"

Dude, he's jam 'n' a biscuit!
Let's go jam 'n' a biscuit!
I gotta go jam 'n' a biscuit.
Dude, I just jam 'n' a biscuit.
