Its from a old Muppet Babies cartoon where Animal the muppet is called The Great Lamina. It tends to transaltes to people usually a specific person who is an unorthadox maniac especially in sports. Like really short people in basket ball who ram the tall people in the balls with their heads on a lay-up to prevent getting rejected.
Oh crap darnell is covering the hoop! Its ok, just give it to the great lamina and he will just peck him in the balls with his head.
