smegma
A formidable cheese-like residue that builds up between the foreskin and the penis resulting from lack of personal hygiene around the groinal crotchable area. 

Side note: While smegma may be reminiscent of a domestic cheese, ball sweat smells like mayonnaise!

Smegma may taste like pumpkin pie, but I'd never know 'cuz I'd never eat the mutha' fucka'.
