Is it JUST ignorance and superstition, or might there actually be an environmental factor at play here? Could these people perhaps be unknowingly ingesting something psychotropic like ergot or some other naturally-occuring hallucinogen? What about the geologic angle--some sort of Earth-borne gases or heavy metals? I just can't accept "ignorance" as a rationale when it comes to killer snails.
I can't imagine how people could believe in such a thing. "Magic Penis" tsk! tsk! tsk!
Perhaps they heard Lil' Kim & 50 Cent's song "Magic Stick".
"I got the magic stick
I know if I can hit once, I can hit twice
I hit the baddest chicks
Shorty don't believe me, then come with me tonight
And I'll show you magic
(What? What?) Magic (uh huh uh huh)
I got the magic stick"
