Throw some potting soil on the ground and while having coitus in the doggy style position with your partner they pretend to be gardening. When finished sprinkle some dirt on their bootyhole and place a seed in the dirt, then plunge the seed in with your thumb.
My boyfriend gave me the green thumb last night, and now I have a green bean growing out of my anus.

Defined as the act of releasing one’s bowels in a manner where the shape of said excrement perfectly fits into the bottom of said toilet, plugging up the hole well enough to prevent successful flushing.
