A semi chubby penis, particularly when a male is lying in a bath. The penis sticks up out of the water like a snorkel, creating a cross between a penis and a snorkel. A penorkel.

Also used to describe one of lesser intelligence.
Wow, look at my penorkel. My penorkel is coming up for air.

You are such a penorkel.
