Poopkin refers to the "mud people" written in Genesis in the Christian Bible. This refers to muslims (Duners), their homosexual deity Mohammed (who loved to eat ass and take loads on his stupid jizz encrusted beard), and dark skinned people.
The poopskins love welfare and crack. Poopskins commit more crimes than actual people.
Look at that stupid poopskin kneeling on a mat worshiping mohommad and his stupid beard full of jizz.
