The act of swaffling (smacking your penis against something) fast and furiously between a woman's breasts. Similar to motorboating but with a penile element.
You could motorboat your girlfriend, but may derive more pleasure from pontooning her instead. Just make sure it is ok to ejaculate in her cleavage before doing so.

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?"
