Is He The "Old-Ass Rapper" Lil Wayne Is Rapping About? If Wayne didn't call Birdman "daddy," we're pretty sure he would be one of the old-ass rappers Wayne called out. Seriously: Why is this guy still making music? Isn't he eating well enough off Cash Money artists to chill out on creating new tracks? But, of course, Wayne does call Birdman "daddy" so this is a mute point. Weezy is definitely not picking on him.
