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.
OK girls I need to get some action tonight.......NO BOX BLOCKING!
