Well, if you're serious about pulling white girls, they're all into being wh0red-out fag hags nowadays. You know, the whole lez pole dancer sh1t.
Seriously, punk it up. Wear lots of earrings, gelled, colored hair, fruity clothes, and talk sissy. Go up to girls and say you love their scarves and you'd like to go shopping with them. Don't forget to say "F00000CK" all the time as lezbians do -- it's their mating call.
