When a guy is fingering a girl and he is so bad at it that he slips it in to hard and fast or Pushes to hard it becomes painful and uncomfortable for the female so much so she actually has to have him stop! A girl only has to have this happen once to never let him try that again!
Amy: So how was your night with Benny?

Vicky: Not so great he had a bit of a Finger Fumble..

Amy: Wow guess that was a short lived relationship!
