So my girl don't see me T-Pain, can I get those keys to the car?

from T-Pain (Ft. Akon) – Bartender Lyrics on Rap Genius

Meaning

Akon came to the club with a girl (in fact saying “my girl” implies a long-term thing, which can’t happen with a new girl), which is why he rarely comes out. However, he starts singing to a girl, and decides to leave with her. He asks T-Pain to give him the keys to his car before his old girl sees him, so he can escape with his new one.
T-Pain has a good amount of cars so Akon could probably get one
