When one has two pussies stacked one atop the other, for easy alternating insertion. Usually done doggystyle, this position is used mostly in FFM (female-female-male) porn.
Did you see Ava Devine and Alica Saint in that new Peter North flick? He stacked their asses up into double decker pussies and fucked them both, man!

Possibly the worst invention in history. The double decker outhouse is, quite literally, two toilet stalls stacked. Although this structure conserves space, it is completely impractical and downright messy.
Bottom stall occupant: What's that creaking?
Morbidly obese top stall occupant: ... I think the floor is caving in.
Bottom stall occupant: *Sigh* ... who in their right mind invented the double decker outhouse?
