Purple Santorum 

A sexual act performed through the female eating a high enough quantity of beets to turn her feces purple, and quite possibly staining her butthole. The male then penetrates the newly dyes purple butthole with his penis, creating the Purple Santorum.

My girl is chowing down on some beets right now, I'm getting a Purple Santorum for my birthday!
