Like "Stop it 5" or "Stop it, man" it means "stop that crazy, ridiculous, fucked up thing you're saying" -- with some added flourish. And like the "5" in Stop it 5," the "B" may once have referred to the Bloods street gang, or just may just be short for "blood."

Stop it B is also a popular catchphrase used by comedian Felonious Munk.
"Stop it B... You ain't all that, and none o' those shorties are interested in your broke ass."
