(noun) Spontaneous Generation. People originally thought larvae randomly appeared on poop, and mold randomly grew. Or, more correctly, spontaneously generated. This is now known to be false, but is a theory still taught in school. Some teenagers like to use it as a sort-of-funny explanation.
Man A: How'd that dog crap get on my bed?

Man B, who had put it there because Man A is such a neat freak: Must be abiogenesis.

Man A: What's that?

Man B: You know, Spontaneous Generation? Just randomly grew out of nothing.

A modern theory describing how ancient abiotic macro molecules could spontaneously begin to self replicate and evolve, eventually forming living organisms.
Guy a: "Evolutionists believe in spontaneous generation, that living organisms popped out of non living matter"

Guy b: "No, they believe in abiogenesis, the theory that explains how naturally occurring macro molecules could begin to replicate themselves and evolve."
