Asshole Terraforming 

The process of destroying someone's asshole so completely that afterward a terraforming process can take place to make the ass capable of sustaining life.

I forgot to get my viking wife a valentines day gift, so she proceeded in Asshole Terraforming so brutally that half of our livestock now live there, complete with a chemically stable atmosphere.
