A psuedo-scientific measure of the maximum capacity of a room for retardation/retarded behavior.
Using a soldering iron to fix a broken support beam in a futon almost breaches the retardacity limit in a given room.

"This room has reached its retardacity limit. If it gets any more retarded something will probably catch on fire."
