A level of "b's" standing for the word bitch to describe the level of how much you hate someone. The levels go from B.1-B.9. If someone is ultimately gay they are called a "C" which stands for cunt because its the most offensive word in the english language I hear.
Michsa from Wal-Mart is a B.7.
Maggie's B level was elevated to B.4 when she wouldn't suck my rag.
