an erection that comes for no reason. it just happens. you could be in the locker room with a bunch of dudes. dont worry if it happens there. as long as it only happens once youre probably not gay, just unlucky.
its a quiet day in penisville. some young sperm cells have crawled into the penis and are playing in the veins.
Cell 1: Hey, whats that sound?
Cell 2: surprise boner!
Cell 1: The blood wasnt supposed to come till we see the hot chick on the bus!
Cell 3: DIVE!

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?"
