Phantom Load

The mysterious (and some say, nonexistent) phenomenon, sometimes known as the faked male orgasm, is better known as a phantom load.

"The strangest thing happened."
"What?"
"After sex, last night I saw the condom John used, but it was... empty."
"How could that be?"
"I know, it's so weird! He acted like he finished, but I guess it was just a phantom load."
