double tubbing
the act of middle aged couples bathing al fresco in side by side tubs. a stunt intended to be erotic posed by people least likely to pull it off, never mind tear it off. an unlikely scenario proffered for your consideration by the manufacturer of an erectile dysfunction palliative.
hey, babe, i think i'm feeling froggy. lets throw all restraint to the winds and give ourselves completely to this moment of passion if we can find two tubs side by side somewhere in the open air. i'll give you a drubbing in some double tubbing.
