Quality House is the pinnacle of drink mixing technology crafted by the gods. First you take Motts applesauce (must be Motts otherwise it wont be a solid and might actually be possible to drink) and mix it with Bacardi rum. Then you find any two flavors of Izzy lying around your house and add those in. The final step, and arguably the most important, is to shot gun a beer into your face and completely ruin someone's bathroom by short circuiting their electrical outlets. The smell of burning plastic is VERY important as it adds to the ambiance of the moment.
It is also important to mention that Quality House can also be operative as an adjective (ie. The women love my dick it is so Quality House, or, This quality house is so Quality House (I see wat u did thar (holy shit parenthesis in parenthesis in parenthesis)).)
