The
penis [syn: prick, dick, shaft, pecker, peter, tool, putz].
The use of the word cock-up to mean a blunder or error
was originally British military slang dating from the
1920s. The human penis differs from those of some other
mammals as it has no baculum, or erectile bone. The human
penis relies entirely on engorgement with blood to reach
its erect state.
Did
you know that the human penis is larger than average in
the animal kingdom in proportion to body mass?
