Based on the classic urban pastime of exchanging 'Yo Mama' jokes with your friends, this collectible trading car version features 150 different 'snaps', complete with point rankings. Challengers can compete by trying to outrank each other by having an audience decide which insults are the funniest. Rare 'Oooh!' cards are randomly inserted into packs, allowing players to make up their own jokes. - BoardGameGeek
