Who they attracting with that line, 

"What's your name, what's your sign?"

Biggie is one smooth operator.  He knows better than to use lame pickup lines like "What's your sign?" -- as Rap Genius explains, "he knows that girls just want you to ask open-ended questions so they can yap away."  And he knows to wait until the "What's your sign" guy buys his target a drink so he can save a few bucks.
