The female version of "C-Block". This can occur 1 of 3 ways:
1)A male friend begins a conversation with you at the most inoportune time.
2)A female friend brings up a conversation topic that is typically spoken between women (i.e yeast infection, menstrual clot, etc.).
3)or another hoochie scoops in on the fella you have eye ballin all night.

Much like the term cock block for men; the Box Block is the reverb for a female. Defining the actions taken when one female steps in front of another female to void a sexual advance from a man.
