British slang, very similar in meaning to razzle. It means going out, getting pissed, but the major objective is lots and lots of shagging preferably with a number of different partners. As with razzle this slang term has its origins with the Royal Navy but became more widely known due to the Kate Bush song “Ran Tan Waltz”.
Joe’s in his pit, snoring his head off. He spent most of the weekend on the ran tan.

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?"
