Killing two turds with one kidney stone

Exactly the same definition as "killing two birds with one stone", but this term can be used as a more vulgar/edgy next level substitute to get the same point across, but also cause a sense of shock and awe also possible disgust towards first-time listeners of this phrase. This phrase may also invoke the mental image of a man grabbing his own penis and tilting it upward like a firearm and shooting out a kidney stone with such intense force that it could lethally penetrate two flying turds with bird wings killing them both at the same time.
