But you used the words "mother ****er" to put across the size of your hangover. Surely that's not a medical term.
it is look in the lancet
Oxford English dictionary definition
1. motherfucker
A common slang derived most popularly from a form of "yo momma jokes" but actually dating way back to the 1300's when it was considered the highest sin to sleep with ones own mother. (Even above murder.)
It can mean precisely as it sounds, one who has sex with mothers, but it was originally meant as "one who has sex with their own mother".
It is most of the time used without meaning, just to be said in a sentence, it can mean absolutely nothing and absolutely everything its meant to at the same time.
Also is used constantly to denote someone is a moron, a trife, a back stabber, and any number of other completely unrelated meanings.
"You motherfucker! how could you!"
"What the motherfuck is going on here?"
"Motherfucker, motherfucker, motherfucker...!"
Also described in the influential medical journal The Lancet where Famous Neurosurgeon Ben Carson described a patients brain trauma as 'nothing more than a mother ****er of a hang over'
