Song on MTV's Sucker Free Countdown Commercial?

It's a rap song & the chorus goes like "I just call her boo, I don't know her whole name...Keep it on the low mane." Then later in the song he says "She be smokin on my reefer mane." It was during the Sucker Free Countdown but it was like a commercial..? In the video the guy's just driving a car the whole time. Anybody know what song this is?????? PLEASE HELP! Thanks (:
