Well, that type of storm system had its name long before the Seth Rogen movie, but you are smart and I am pretty sure you already knew that so I don't know why I bothered posting this up for you.
Wasn't that the reason the bud(and movie the bud was in) was called "Pineapple express"? Because the storm system had something to do with the way it was grown? Maybe I'm just really high, but I think I know what I'm talking about.... been wrong before though.
