Not to be confused with a tactical fart.

A TAC-fart is the acronym for a "top arse crack" fart. These are specific farts that are funnelled up the arse crack and expell themselves out the top of the trouser band, onto the lower back.

They are often of a high pitched squeaky tone and best performed when sitting on a hard, flat surface where the air has no way to move forward from the anus, thus must escape via the top of the arse crack.
Nice TAC-fart, you could have warned me though my mouth was open.

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?"
