Rabbit dust
small raisiny bits of colonic cargo that get stuck under the foreskin and look like the "dust" i.e poo. that rabbits leave all over the countryside. ruining it and not one of the little bastards gets hanged for it!! not even a bloody fine!!
oh christ love!! can you get it all out before i do that again, i'm covered in rabbit dust!! but i still love you i suppose. hmmm
