British Army acronym describing urban warfare, it stands for Fighting In Someone's House & Causing Havoc In People's Streets. It probably comes from some squaddie saying that urban warfare was fighting in someone’s house, another realised that it spelled “FISH”. The logical thing, given the British soldiers’ sense of humour would be to add “& CHIPS” and find something appropriate to match the letters. Strictly speaking that makes it a bacronym, but a remarkably appropriate one for all that.

When a woman's vagina smells like an sea creature and a man, who is turned on by this foul odor, takes a potato chip, preferably Lay's brand, and dips this into the vagina, stimulating the woman's clitoris. When the woman has orgasmed, the man takes the now soggy potato chip out of the vagina and eats it, signifying the conquering of the woman. In the mid-1500's, kings of England would use this technique to make a female "their bitch". However, they used a chicken wing and the procedure was much more painful for the woman.
"There was a midnight buffet of fish and chips last night."
