If you look closely, past the cock (I mean the rooster, ya nasties), you can see what the designer was trying to achieve with each half representing a lowercase "D" and "B" for Dirty Bird and by adding a single eye (insert inappropriate dick joke here), neck feathers (uh, dem is pubes), a beak, and comb (I'm just gonna leave this Jizz In My Pants link right here), designer Mark James thought he was being creative by turning a linked set of boring initials into a rooster. Which he did, kinda.
