When you are with a bunch of your friends and one of them makes an audible fart. At this time you or another one of your friends silent farts and then blame the smell on the friend whose fart was heard
Its a well known fact that when a guy farts, a girl will silent fart and double up on the guy so he gets the blame.

In sleepovers, it's the act of having to sleep next to someone of the same gender in the same bed.

The term doubling up is commonly used to make the one using the word seem less of a homosexual, as saying "Let's sleep togeether." Can spur awkwardness.
We need to double up, tonight. Just make sure we don't look eachother in the eyes.
