I went and looked it up. There's no recording of it or anything, just anonymous sources repeating what he said during a private dinner Republican legislators were having to discuss domestic violence legislation, but apparently he has a huge reputation for saying stupid offensive crap.
The full context of the quote, from what I've read, was that he made some joke about women being best kept "at home baking cookies" or "barefoot and pregnant," then saying to Katrina Shealy (another South Carolina senator, and the only woman at the event, who was elected in 2012) that he saw it only took him two years to get her to wear shoes. Clearly he thinks he's a funny guy. She responded by asking where he got off making such remarks, and he replied with the cute quote in the image.
The other big stupid thing he said that made news, back in 2013, was at another meeting of the SC Republican senators, this one discussing a federal education bill. He gave an anecdote about how when he was in school some teacher talked about tribes in which the elders make younger men fellate them and consume their semen (which is true, a couple tribes in Papau New Guinea do this because they believe it contains some kind of masculine essence and eating it will make young men grow up big and strong and manly), and he used the term "gay man juice" during the explanation. Apparently learning about real facts of the world was offensive and inappropriate and solid proof as to why the federal government should stay out of education.
So yeah, dude's a grade A dipshit. Having lived in the United States all my life, I must sadly say that I am not at all surprised that he made it to the state Senate. There are even worst guys at the national level, after all, and George W. Bush said bonkers shit like this on a regular basis. I have become inured to politician stupidity, it seems.
