I've just heard the song 'World War III' from the All Out War mixtape (which you can listen to here) and Yukmouth says in the third verse : "Imma have the last laugh/My cousin signed to Aftermath/One phone call I'll have them muthafuckers clap your ass" What the fuck is he talking about? BTW he's dissin Afroman in the same song (at the end of the first verse), why?
