The mainstream press were gaggling around White House press secretary Scott McLellan and CBS News White House correspondent John Roberts had a question about Judge Sam Alito:

“Scott, you said that – or the President said, repeatedly, that Harriet Miers was the best person for the job. So does that mean Alito is sloppy seconds, or what?�

“Sloppy seconds”? From A Dictionary of Slang:

Noun. A subsequent indulgence in an activity by a second person involving an exchange of bodily fluids. This may involve the sharing of drink, or more often it applies to a sexual nature. E.g.”I’m not having sloppy seconds, I want to shag her first.”

Roberts’ apology is posted at that CBSNews blog. In part:

At the morning White House gaggle, I used an unfortunate choice of words in a question to Scott McClellan. Please be assured that there was no perjorative [sic] intent to my question. I was merely attempting to reconcile past statements about Harriet Miers with the President’s new nominee for the Supreme Court. …

About exchanging bodily fluids?

Perhaps CBS News’ Roberts is a “sicko”"

Noun. A disturbing and unsavoury person, a pervert.

Indeed.
