Vitamin F stand for floor and is when food or drink falls on the floor and you pick it up and eat it or drink it. It doesn't matter if it passes the so called "5 second rule", the moment it hits the floor, it has vitamin F. The floor has germs and sometimes viruses. The dirtier the floor and the longer it's been on the floor, the more vitamin F it has.
*Soda and hamburger falls on the floor.
Frank: *Picks up hamburger and eats it and uses straw to drink the soda.

Frank: Vitamin F!
Daughter: That's filthy!
*Frank has a Frank Moment.
*Frank ends up getting really sick.
