look up any word, like pussy:

1 definition by Presidential Jeff

n. The resulting low hanging, loose, flappy labia from muliple bangings of the female genitalia, a floppy used vagina that has been wrecked and destroyed by many people.

It's floppy and it wobbles - hence flobble.
"Wilma's flobble was so long that she could tie it in a knot."

"I was doing this slut the other day and her flobble was hanging almost to her knees."
