[1] Pizzle is a Middle English word for penis, derived from Low German pesel or Flemish Dutch pezel, diminutive of pees, meaning 'sinew'. The word is used today to signify the penis of an animal, chiefly in Australia and New Zealand.
[2] Interestingly, it is used in medical slang (Dictionary of medical slang -Jacob Edward) and it is defined as exhausted, or to its point:
~ Pizzle chewer ... A female who relieves a male of his phallic tension by fondling the instrument in her mouth.
~ Pizzle-grinder ... 1. A butcher. 2. A prostitute.
~ Pizzle honker ... A prostitute who satisfies her patrons by manual friction.
~ Pizzle warmer . . . The pudendum muliebre, esp. the vagina.
~ Pizzled . . . Exhausted physically or mentally.
So I guess you could say that Pocket is a Fizzled[3] Pizzle.
In the 19th C it was a word in the West Country dialect Thomas Hardy knew well, and appears in Jude the Obscure to describe the pig's member that is thrown at Jude. Apart from this description, it gets called "that part of the pig which is thrown away" and other euphemisms, so I suppose Hardy must have thought pizzle was already obscure enough not to get him into trouble.
