Cok O Pops
Cok O Pops is a breakfast cereal manufactured by Biglogs, seen advertised in Grand Theft Auto: San Andreas and Grand Theft Auto IV. The cereal's slogan is "Start your day with a mouthful of cok!", which is a reference to oral sex. The cereal's name is a reference to real-life cereal Coco Pops, while the usage of a cockerel mascot is a reference to Corn Flakes (the Cok O Pops chicken is being choked, a euphemism for masturbation).
