If you ever got two chicks both with dizzy legs bring 'em both and do a double up on 'em, dawg!
Kiss me; now kiss her; we do the double up like that!

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.
