A genetic disorder in which a female's breasts are extrodinarily larger than the size of the individual's head.

To determine whether or not a female has canoons, you will have to calculate the radius of one entire breast, and multiply it by 3.14 to get the external surface area. Compare the surface area of the head to the surface area of the breast and if the breast is larger than that the surface area in that of the head, than the female infact has CANOOOOOONS.

(in extreme cases, it is possible for males to have canoons)
Breast Size = 30cm(square)
Head Size = 15cm(square)

Conclusion
Since the breast size is double the head surface area, this person would have canoons.

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?"
