1.
The word ‘fannon’, generally regarded as an unstable neologism but gaining popularity as a slang term in parts of East Anglia (United Kingdom), is a noun or concept - often used in general conversation – having the literal meaning of a tear in the perineum which conjoins the vagina and the anus, giving the appearance of one orifice instead of the biologically normal two. Fannon can also be used as a technical term, when this rip occurs due to accident, operation, birth or extreme penetration.
