When one shits on the ground, and another shits on top of the original shit. Usually very steamy and mountainous.

Short for bullshit stacking. It's a tactic bullshitters use to place a large enough stack of BS consecutively to basically exhaust the willingness of a rational person to unpack it. It's followed by the bullshitter using that lack of willingness as a "victory" for their viewpoint. It's a consequence of Brandolini's law. See Liz Wheeler and Jordan Peterson as shining examples of this tactic.
From facebook, today: "don't claim to be a spiritualist if you bash others beliefs and religions ... you may not do those things under the white light of god but i sure do, especially tarot readings. Do yall know the portals you can open up doing that?? so yes i go by god he is my protector and this is exactly why you guys need educated before speaking on things."
Me: Wow that's too much shit stacking for me to bother unpacking it.
