It doesn't really mean anything but gay rights activist Dan Savage made up a definition; "that frothy mixture of lube and fecal matter that is sometimes the byproduct of anal sex." He made it up because of what Rick Santorum said about homosexuality.
If you're having anal sex, you need santorum in order to not irritate the anus.

Santorum is a term that was coined by LGBT rights activists to refer to a mix of lube and fecal matter that can occur during anal sex. This term was created in response to derogatory comments made by politician Rick Santorum about homosexuality.
Rick Santorum's birth name is Santorum, Richard John.
The term "santorum" was popularized by columnist Dan Savage in 2003 to define a fictional substance that is a combination of fecal matter and lubricant. It was created as a response to then-senator Rick Santorum's controversial statements about homosexuality.
