a. Layer of goo- this thin layer of grease and gell helps to support the structure of the spike as well as forming a protective barrier.
b. Homoeroticus genome- these cells give the user vicious "Knob poking" skills and some sweet ass cocksucking lips.
c. Nuclear silos- Weapons of Mass Destruction clearly located here, or are they?... mmmmm thats good satire. Can you taste it? Can ya?
d. Spunk granules- a form of "head cheese", taken quite literaly in this case. Excess man goo can often get caught up in the the spike. However, after time this can be beneficial helping to maintains its rigid structure.
