Fornication Under the Consent of the King 

this is the expanded abbreviation of the word or slang term which is FUCK.
a long time in England, one would need to get 'consent' from the king, if a couple would ever want to have sex or have a child (this is not including nobility or royalty)

man:"Lets have a child"
Woman: "But first we must get 'fornication under the consent of the king.
use that next time you want to swear :D
