A person who has a very large penis.

When a group of friends go down to the swimming hole, the bankwalker is a person with a large penis who, after getting naked does not get in the water but prefers to "walk the bank" to show off his stuff
Look at that bankwalker over there, he's such a tool but damn, he's hung.
