pistachio nut surprise 

when someone eats a series of food to make there poop green and then smashes their white asscheeks against a window and releases its green caca surprise all over the window resembling a pistachio nut. (green caca+white asscheeks= pistachio nut surprise)

i pistachio nut surprised my mom the other day and she broke the glass window making my anus bleed.
