Once again I reference Merriam-Webster online.  The definition of PHALLUS is simple:

“a symbol or representation of the penis”

Because a picture is worth a thousand words, I have opted to illustrate the meaning with pictures rather than words.  (You may also want to note that most of these phallic buildings are financial institutions–that are boning us–coincidence?)

While some of these look rather painful, they all required quite a bit of engineering…  🙂
