It’s like poetry
Santorum is defined as: The frothy mixture of lube and fecal matter that is sometimes the byproduct of anal sex. This definition was popularized by the American humorist and columnist Dan Savage, in 2003 and is named after US Republican Senator Rick Santorum from Pennsylvania.
It emerged after Savage reacted strongly to Republican U.S. Senator Rick Santorum’s controversial statements about homosexuality in an interview with the Associated Press published April 20, 2003. In the interview, Santorum classed gay sex together with incest, polygamy, and bestiality as deviant sexual behavior threatening society and the family. Santorum further stated that he believed consenting adults do not have a constitutional right to privacy with respect to sexual acts.
Outraged by Santorum’s statements, Savage challenged the audience of his column Savage Love to come up with a sex-related definition for the word santorum with the stated purpose of “memorializ[ing] the Santorum scandal […] by attaching his name to a sex act that would make his big, white teeth fall out of his big, empty head”.[1] After Savage published several definitions suggested by readers, a vote was taken among the readers of his column. Savage announced the winning definition in his June 12, 2003 column.
