Not as in "Shhh...the baby's sleeping." More like "Mike is sleeping with his secretary!" or "Representative X is sleeping with her husband's accountant!"
C'mon guys. Especially the press. Shirley there is another way to get across that someone is screwing someone. Why "sleeping" for fertheluvvadog? That's the last thing that those people are doing. They're humping like dogs in heat! They are dancing the horizontal tango, they're bumping bellies, making humma humma. They're bloody exercising!
How about that? In future use the term "exercising" as a euphemism for making the two backed beast?
I like it! "Senator Y is exercising with a reporter from Fox!"
