Double Stacking

When someone sits on the toilet and another person sits on their lap to shit and uses their thighs as a seat.

Tony was shitting and Sam needed to as well, so Sam sat on Tony and used double stacking to shit.

double-triple

When someone goes to second base on a girl and uses their free hand to go to third base on the same girl.

Sam, after quite some preparation and going to second base with one hand, got to work for real on Sandy by moving a hand to her third base; he was now performing a double-triple.
