When a man urinates on his nutsack due to having an extremely small penis. The urine flows through the awkward crease between a males testicles that is formed by the skin of the scrotum.

In other words, you cockola is too short to refrain from pissing on your nuts. Therefor causing the piss funnel.
"After getting stung by a jellyfish I really needed someone to piss all over my leg. I preferred not to get piss anywhere else except my leg. Thank God Tom came to the rescue with his piss funnel(small cockola) and provided a neat single stream with no splatter." Thanks Tom.
