A game started by a Lil' Jimmy Norton. When it begins to rain, someone yells "The monster rain is coming." You then hide underneath the porch and perform fellatio on your friend, who then returns the favor.
Lil' Jimmy watched the weather report with great excitement, in hopes that a low pressure system would bring the Monster Rain.

A childhood game played by young boys. You hide from this imaginary rain by running under the porch and giving each other oral treats.
Why don't you invite Jimmy Robinson over to play monster rain?
