hehe, lame men
I read this definition in another post: Knock/Detonation is the spontaneous combustion of the end-gas (remaining fuel/air mixture) in the chamber. This occurs after the spark.
So, if you are running too rich then there would be even more "end gas" to ignite, which would make the possibility of detonation higher or more severe.
