doppleknockers
Two random women having the same bosom.
I was at home depo with my wife and some other dude says "Hey Megan", clearly addressing my wife (named Maria), "These are on sale" (pointing at the endcap). His wife (who is behind him) turns and looks at him. I notice she is wearing a scallop necked halter top similar to my wife's. Both cleaves were indistinguishable from the other. They were doppleknockers.
