When u tryin to get dis fine ass girls attention and number

A line that the famous Viner King Bach uses as a pickup line. It obviously means let me get your number.

When you get something and someone that is close to you asks for some.

wagwan = whats up
piffting = hottie (girl)
bbm = black berry messenger

so back in the days when blackberries still were a thing you had to get a code to DM someone. so this is actually just a really special way to say: whats up girl lemme get your number.
