A "flap-p-ie-cou-pap-p-y" is a very large vagina, in danger of the uterus
falling out.
It happens a lot in the
old folks homes, but can be attributed to "whore", "slut", or "loose", woman...
"That flappycoupappy better have my money!"
"Tommy's
Grandmother has a enormous flappycoupappy, and the
the janitor isn't so happy..." :(
"I had a dream
last night, about your flappycoupappy..."
"What'da ya say we go back to the loft and I'll sew up that flappycoupappy'uh yours..."
