Dallas Phallus 

Slang term for the penis-shaped Reunion Tower in Dallas, Texas. Symbolic for Texans' often-times hubris and macho behavior.

We drove through Dallas-Fort Worth metro area today and I was able to capture a great picture of the Dallas Phallus.

Don't call it a fat cock. Call it a magnum phallus. It's classier that way.

sunk cost phallus 

When you go through the work of setting up a hook up with a dude and he turns out to be much less than advertised in person, but you decide to go for it anyway.

I distinctly stated "no fatties" on my profile but better the bear in here then the bear out there, guess I'm committing a sunk cost phallus.

The instrument through which an eye-floating pee is finally released...the stream producing a roar in the pan similar to the famous falls

Bloke in pub: Where did you disappear to?
Relieved one: Just been to see Niagara Phallus.....sigh

Poisoned Phallus 

A gentleman’s throbber which, when excited, emits a sour, curdled, vinegar like load with the capacity to poison its recipient (if any). Always point away away from face.

Ste presented Shaun with his poisoned phallus whilst Trev willingly watched on.
