Wingwang

We'll take someone else's word for this one: in All the Fine Young Cannibals (1960), a film which we hear is so bad that one just can't sit through it, Robert Wagner's wingwang can be seen to visibly wigwag through the fabric of his trousers.

“This man —I can’t tell you his name — has thick black hair growing on both sides of his wingwang.” She stopped and blinked. “There, I said it.” “Goodness, gracious, sake's alive! His penis?” “Yep.”
