An unusually large penis. Large in both length and girth. A Godzilla Penis is said to be so good it can actually rip a girl in half, not simply make her feel like she's being ripped in half.

In Japan, the Godzilla Penis is a legendary penis, said to belong to a hero who will save the world from destruction.

EXAMPLE 2:

"Long ago, a prophecy foretold of a hero from a land far to the east saving the world with his giant penis. A penis of Godzilla proportions. Known as the Godzilla Penis."

Aug 11 Word of the Day
A phrase to describe someone who is cognitively degenerating. Synonym of "going off the deep end". Can have varying degrees of severity.

Reference to the song "Hey You" by Pink Floyd. The line "and the worms ate into his brain" makes no sense in an otherwise linear and literal narration throughout the lyrics.
"My boyfriend has a total case of brain worms. He told me the cat was bugged so the Feds could listen in on us having sex..."

or

"You totally stumbled over that entire sentence. Can't speak English all of a sudden? What, do you have brain worms?"
