mississippi oil rig 

A dirty deed indeed. The male must first start eating fried chicken with waffles, while simultaneously drilling the female anally. After a few minutes of relaxing the female's sphincter, the man should pull out, immediately followed by the female having explosive diarrhea everywhere (this can be aided by giving her a laxative and a chipotle burrito before hand). The bursts of fecal material coming from her anus will resemble oil shooting up from the ground.

Guy: Dude my girlfriend and I did the mississippi oil rig yesterday and completely destroyed my sheets.

Other guy: Why are you talking to me?
